How to detect Safari, Chrome, IE, Firefox and Opera browsers?

I have 5 addons/extensions for Firefox, Chrome, Internet Explorer(IE), Opera, and Safari.

How can I correctly recognize the user browser and redirect (once an install button has been clicked) to download the corresponding addon?

I use bowser https://github.com/bowser-js/bowser

const objBrowser = bowser.parse(window.navigator.userAgent);
console.log(objBrowser);
$('#browser').text('Browser: '+objBrowser.browser.name+', Version: '+objBrowser.browser.version);
$('#os-platform').text('Run On: '+objBrowser.os.name+' - '+objBrowser.platform.type);
<div id="browser"></div>
<div id="os-platform"></div>

Perhaps the real answer is that 90% of the time, you can't reliably detect any specific browser.

The most reliable way for your use case is to provide a download button for each browser and let the user - who knows for certain what browser they are on "tell you." All of the detection methods shown in these other answers will either eventually stop working, or can easily be faked.

User-agent strings can be overridden by the user.

Browsers, over time, trend toward removing unique API differences. (Source: look at Internet Explorer over the years)

If you must use browser detection, use a well-updated library to do so. So long as you keep that library up-to-date, you can be assured that the detection will not fail - so long as it's not too reliant upon UA strings.

For other use cases, don't use browser detection - use feature detection. Modern Firefox supports everything - if not more - that Chrome does, and generally is closer to the w3 & etc. specs. A tool called "browserlist" is a great tool to determine which browsers' features your code should use. Tools like Webpack, Parcel, Babel, and more use this - so you can use the latest browser features without having to write the compatibility code yourself.

const getBrowserName = () => {
    var userAgent = navigator.userAgent;
    var browser_names = ['Firefox', 'Chrome', 'Safari', 'Edge', 'Opera', 'MSIE', 'OPR', 'Trident/']
    var browser_name = "Unknown Browser"

    for (let i = 0; i < browser_names.length; i++) {
      if (userAgent.indexOf(browser_names[i]) > -1) {
          browser_name = browser_names[i]
          return browser_name
      }
    }
    return browser_name
  }

Less verbose than others

You can try the following way to check the browser:

function myFunction() {
  if ((navigator.userAgent.indexOf("Opera") || navigator.userAgent.indexOf('OPR')) != -1) {
    alert('Opera');
  } else if (navigator.userAgent.indexOf("Edg") != -1) {
    alert('Edge');
  } else if (navigator.userAgent.indexOf("Chrome") != -1) {
    alert('Chrome');
  } else if (navigator.userAgent.indexOf("Safari") != -1) {
    alert('Safari');
  } else if (navigator.userAgent.indexOf("Firefox") != -1) {
    alert('Firefox');
  } else if ((navigator.userAgent.indexOf("MSIE") != -1) || (!!document.documentMode == true)) //IF IE > 10
  {
    alert('IE');
  } else {
    alert('unknown');
  }
}
<!DOCTYPE html>
<html>

<body>
  <p>What is the name(s) of your browser?</p>
  <button onclick="myFunction()">Try it</button>
  <p id="demo"></p>

</body>

</html>

And if you need to know only IE Browser version then you can follow below code. This code works well for version IE6 to IE11

function getInternetExplorerVersion() {
  var ua = window.navigator.userAgent;
  var msie = ua.indexOf("MSIE ");
  var rv = -1;

  if (msie > 0 || !!navigator.userAgent.match(/Trident.*rv\:11\./)) // If Internet Explorer, return version number
  {

    if (isNaN(parseInt(ua.substring(msie + 5, ua.indexOf(".", msie))))) {
      //For IE 11 >
      if (navigator.appName == 'Netscape') {
        var ua = navigator.userAgent;
        var re = new RegExp("Trident/.*rv:([0-9]{1,}[\.0-9]{0,})");
        if (re.exec(ua) != null) {
          rv = parseFloat(RegExp.$1);
          alert(rv);
        }
      } else {
        alert('otherbrowser');
      }
    } else {
      //For < IE11
      alert(parseInt(ua.substring(msie + 5, ua.indexOf(".", msie))));
    }
    return false;
  }
}
<!DOCTYPE html>
<html>

<body>

  <p>Click on Try button to check IE Browser version.</p>

  <button onclick="getInternetExplorerVersion()">Try it</button>

  <p id="demo"></p>

</body>

</html>

Short variant (update 10 july 2020 mobile browser detection fix)

var browser = (function() {
    var test = function(regexp) {return regexp.test(window.navigator.userAgent)}
    switch (true) {
        case test(/edg/i): return "Microsoft Edge";
        case test(/trident/i): return "Microsoft Internet Explorer";
        case test(/firefox|fxios/i): return "Mozilla Firefox";
        case test(/opr\//i): return "Opera";
        case test(/ucbrowser/i): return "UC Browser";
        case test(/samsungbrowser/i): return "Samsung Browser";
        case test(/chrome|chromium|crios/i): return "Google Chrome";
        case test(/safari/i): return "Apple Safari";
        default: return "Other";
    }
})();
console.log(browser)

Typescript version:

export enum BROWSER_ENUM {
  EDGE ,
  INTERNET_EXPLORER ,
  FIRE_FOX ,
  OPERA ,
  UC_BROWSER ,
  SAMSUNG_BROWSER ,
  CHROME ,
  SAFARI ,
  UNKNOWN ,
}

const testUserAgent = (regexp: RegExp): boolean => regexp.test(window.navigator.userAgent);

function detectBrowser(): BROWSER_ENUM {
  switch (true) {
    case testUserAgent(/edg/i): return BROWSER_ENUM.EDGE;
    case testUserAgent(/trident/i): return BROWSER_ENUM.INTERNET_EXPLORER;
    case testUserAgent(/firefox|fxios/i): return BROWSER_ENUM.FIRE_FOX;
    case testUserAgent(/opr\//i): return BROWSER_ENUM.OPERA;
    case testUserAgent(/ucbrowser/i): return BROWSER_ENUM.UC_BROWSER;
    case testUserAgent(/samsungbrowser/i): return BROWSER_ENUM.SAMSUNG_BROWSER;
    case testUserAgent(/chrome|chromium|crios/i): return BROWSER_ENUM.CHROME;
    case testUserAgent(/safari/i): return BROWSER_ENUM.SAFARI;
    default: return BROWSER_ENUM.UNKNOWN;
  }
}

export const BROWSER: BROWSER_ENUM = detectBrowser();

export const IS_FIREFOX = BROWSER === BROWSER_ENUM.FIRE_FOX;

Functional algorithm, just for fun:

 var BROWSER =  new Array(
     ["Microsoft Edge", /edg/i],
     ["Microsoft Internet Explorer", /trident/i],
     ["Mozilla Firefox", /firefox|fxios/i],
     ["Opera", /opr\//i],
     ["UC Browser", /ucbrowser/i],
     ["Samsung Browser", /samsungbrowser/i],
     ["Google Chrome", /chrome|chromium|crios/i],
     ["Apple Safari", /safari/i],
     ["Unknown", /.+/i],
 ).find(([, value]) => value.test(window.navigator.userAgent)).shift();

This method is currently valid for detecting all browsers. I quoted the vue-element-admin template

 export function fnBrowserDetect() {
      var browserName = (function(agent) {
        switch (true) {
          case agent.indexOf('edge') > -1: return 'MS Edge'
          case agent.indexOf('edg/') > -1: return 'Edge (chromium based)'
          case agent.indexOf('opr') > -1 && !!window.opr: return 'Opera'
          case agent.indexOf('chrome') > -1 && !!window.chrome: return 'Chrome'
          case agent.indexOf('trident') > -1: return 'MS IE'
          case agent.indexOf('firefox') > -1: return 'Mozilla Firefox'
          case agent.indexOf('safari') > -1: return 'Safari'
          default: return 'other'
        }
      })(window.navigator.userAgent.toLowerCase())
      return browserName.toLowerCase()
    }

UAParser is one of the JavaScript Library to identify browser, engine, OS, CPU, and device type/model from userAgent string.

There's an CDN available. Here, I have included a example code to detect browser using UAParser.

<!doctype html>
<html>
<head>
<script src="https://cdn.jsdelivr.net/npm/ua-parser-js@0/dist/ua-parser.min.js"></script>
<script type="text/javascript">
    var parser = new UAParser();
    var result = parser.getResult();
    console.log(result.browser);     // {name: "Chromium", version: "15.0.874.106"}
</script>
</head>
<body>
</body>
</html>

Now you can use the value of result.browser to conditionally program your page.

Chrome & Edge introduced a new User-Agent Client Hints API for this:

navigator.userAgentData.brands.map(item => item.brand).includes('Google Chrome')

Firefox & Safari don't support it yet unfortunately.

To check for IE browser using following code.

console.log(/MSIE|Trident/.test(window.navigator.userAgent))

OR

var isIE = !!document.documentMode; 

console.log(isIE)

Thank you, everybody. I tested the code snippets here on the recent browsers: Chrome 55, Firefox 50, IE 11 and Edge 38, and I came up with the following combination that worked for me for all of them. I'm sure it can be improved, but it's a quick solution for whoever needs:

var browser_name = '';
isIE = /*@cc_on!@*/false || !!document.documentMode;
isEdge = !isIE && !!window.StyleMedia;
if(navigator.userAgent.indexOf("Chrome") != -1 && !isEdge)
{
    browser_name = 'chrome';
}
else if(navigator.userAgent.indexOf("Safari") != -1 && !isEdge)
{
    browser_name = 'safari';
}
else if(navigator.userAgent.indexOf("Firefox") != -1 ) 
{
    browser_name = 'firefox';
}
else if((navigator.userAgent.indexOf("MSIE") != -1 ) || (!!document.documentMode == true )) //IF IE > 10
{
    browser_name = 'ie';
}
else if(isEdge)
{
    browser_name = 'edge';
}
else 
{
   browser_name = 'other-browser';
}
$('html').addClass(browser_name);

It adds a CSS class to the HTML, with the name of the browser.

Here is my customized solution.

        const inBrowser = typeof window !== 'undefined'
        const UA = inBrowser && window.navigator.userAgent.toLowerCase()
        const isIE =
          UA && /; msie|trident/i.test(UA) && !/ucbrowser/i.test(UA).test(UA)
        const isEdge = UA && /edg/i.test(UA)
        const isAndroid = UA && UA.indexOf('android') > 0
        const isIOS = UA && /iphone|ipad|ipod|ios/i.test(UA)
        const isChrome =
          UA &&
          /chrome|crios/i.test(UA) &&
          !/opr|opera|chromium|edg|ucbrowser|googlebot/i.test(UA)
        const isGoogleBot = UA && /googlebot/i.test(UA)
        const isChromium = UA && /chromium/i.test(UA)
        const isUcBrowser = UA && /ucbrowser/i.test(UA)
        const isSafari =
          UA &&
          /safari/i.test(UA) &&
          !/chromium|edg|ucbrowser|chrome|crios|opr|opera|fxios|firefox/i.test(UA)
        const isFirefox = UA && /firefox|fxios/i.test(UA) && !/seamonkey/i.test(UA)
        const isOpera = UA && /opr|opera/i.test(UA)
        const isMobile =
          /\b(BlackBerry|webOS|iPhone|IEMobile)\b/i.test(UA) ||
          /\b(Android|Windows Phone|iPad|iPod)\b/i.test(UA)
        const isSamsung = UA && /samsungbrowser/i.test(UA)
        const isIPad = UA && /ipad/.test(UA)
        const isIPhone = UA && /iphone/.test(UA)
        const isIPod = UA && /ipod/.test(UA)
    
        console.log({
          UA,
          isAndroid,
          isChrome,
          isChromium,

          isIOS,
          isIPad,
          isIPhone,
          isIPod,
          isOpera,

          isUcBrowser,
        }

Googling for browser reliable detection often results in checking the User agent string. This method is not reliable, because it's trivial to spoof this value.
I've written a method to detect browsers by duck-typing.

Only use the browser detection method if it's truly necessary, such as showing browser-specific instructions to install an extension. Use feature detection when possible.

Demo: https://jsfiddle.net/6spj1059/

// Opera 8.0+
var isOpera = (!!window.opr && !!opr.addons) || !!window.opera || navigator.userAgent.indexOf(' OPR/') >= 0;

// Firefox 1.0+
var isFirefox = typeof InstallTrigger !== 'undefined';

// Safari 3.0+ "[object HTMLElementConstructor]" 
var isSafari = /constructor/i.test(window.HTMLElement) || (function (p) { return p.toString() === "[object SafariRemoteNotification]"; })(!window['safari'] || (typeof safari !== 'undefined' && window['safari'].pushNotification));

// Internet Explorer 6-11
var isIE = /*@cc_on!@*/false || !!document.documentMode;

// Edge 20+
var isEdge = !isIE && !!window.StyleMedia;

// Chrome 1 - 79
var isChrome = !!window.chrome && (!!window.chrome.webstore || !!window.chrome.runtime);

// Edge (based on chromium) detection
var isEdgeChromium = isChrome && (navigator.userAgent.indexOf("Edg") != -1);

// Blink engine detection
var isBlink = (isChrome || isOpera) && !!window.CSS;


var output = 'Detecting browsers by ducktyping:<hr>';
output += 'isFirefox: ' + isFirefox + '<br>';
output += 'isChrome: ' + isChrome + '<br>';
output += 'isSafari: ' + isSafari + '<br>';
output += 'isOpera: ' + isOpera + '<br>';
output += 'isIE: ' + isIE + '<br>';
output += 'isEdge: ' + isEdge + '<br>';
output += 'isEdgeChromium: ' + isEdgeChromium + '<br>';
output += 'isBlink: ' + isBlink + '<br>';
document.body.innerHTML = output;

Analysis of reliability

The previous method depended on properties of the rendering engine (-moz-box-sizing and -webkit-transform) to detect the browser. These prefixes will eventually be dropped, so to make detection even more robust, I switched to browser-specific characteristics:

  • Internet Explorer: JScript's Conditional compilation (up until IE9) and document.documentMode.
  • Edge: In Trident and Edge browsers, Microsoft's implementation exposes the StyleMedia constructor. Excluding Trident leaves us with Edge.
  • Edge (based on chromium): The user agent include the value "Edg/[version]" at the end (ex: "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/80.0.3987.16 Safari/537.36 Edg/80.0.361.9").
  • Firefox: Firefox's API to install add-ons: InstallTrigger
  • Chrome: The global chrome object, containing several properties including a documented chrome.webstore object.
  • Update 3 chrome.webstore is deprecated and undefined in recent versions
  • Safari: A unique naming pattern in its naming of constructors. This is the least durable method of all listed properties and guess what? In Safari 9.1.3 it was fixed. So we are checking against SafariRemoteNotification, which was introduced after version 7.1, to cover all Safaris from 3.0 and upwards.
  • Opera: window.opera has existed for years, but will be dropped when Opera replaces its engine with Blink + V8 (used by Chromium).
  • Update 1: Opera 15 has been released, its UA string looks like Chrome, but with the addition of "OPR". In this version the chrome object is defined (but chrome.webstore isn't). Since Opera tries hard to clone Chrome, I use user agent sniffing for this purpose.
  • Update 2: !!window.opr && opr.addons can be used to detect Opera 20+ (evergreen).
  • Blink: CSS.supports() was introduced in Blink once Google switched on Chrome 28. It's of course, the same Blink used in Opera.

Successfully tested in:

  • Firefox 0.8 - 61
  • Chrome 1.0 - 71
  • Opera 8.0 - 34
  • Safari 3.0 - 10
  • IE 6 - 11
  • Edge - 20-42
  • Edge Dev - 80.0.361.9

Updated in November 2016 to include detection of Safari browsers from 9.1.3 and upwards

Updated in August 2018 to update the latest successful tests on chrome, firefox IE and edge.

Updated in January 2019 to fix chrome detection (because of the window.chrome.webstore deprecation) and include the latest successful tests on chrome.

Updated in December 2019 to add Edge based on Chromium detection (based on the @Nimesh comment).

No idea if it is useful to anyone but here is a variant that would make TypeScript happy:

export function getBrowser() {

 // Opera 8.0+
    if ((!!window["opr"] && !!["opr"]["addons"]) || !!window["opera"] || navigator.userAgent.indexOf(' OPR/') >= 0) {
        return 'opera';
    }

    // Firefox 1.0+
    if (typeof window["InstallTrigger"] !== 'undefined') {
        return 'firefox';
    }

    // Safari 3.0+ "[object HTMLElementConstructor]" 
    if (/constructor/i.test(window["HTMLElement"]) || (function(p) { return p.toString() === "[object SafariRemoteNotification]"; })(!window['safari'] || (typeof window["safari"] !== 'undefined' && window["safari"].pushNotification))) {
        return 'safari';
    }

    // Internet Explorer 6-11
    if (/*@cc_on!@*/false || !!document["documentMode"]) {
        return 'ie';
    }

    // Edge 20+
    if (!(/*@cc_on!@*/false || !!document["documentMode"]) && !!window["StyleMedia"]) {
        return 'edge';
    }

    // Chrome 1+
    if (!!window["chrome"] && !!window["chrome"].webstore) {
        return 'chrome';
    }

    // Blink engine detection
    if (((!!window["chrome"] && !!window["chrome"].webstore) || ((!!window["opr"] && !!["opr"]["addons"]) || !!window["opera"] || navigator.userAgent.indexOf(' OPR/') >= 0)) && !!window["CSS"]) {
        return 'blink';
    }
}

Detecting Browser and Its version

This code snippet is based on the article from MDN. Where they gave a brief hint about various keywords that can be used to detect the browser name.

reference

The data shown in the image above is not sufficient for detecting all the browsers e.g. userAgent of Firefox will have Fxios as a keyword rather than Firefox.

A few changes are also done to detect browsers like Edge and UCBrowser

The code is currently tested for the following browsers by changing userAgent with the help of dev-tools (How to change userAgent):

  • FireFox
  • Chrome
  • IE
  • Edge
  • Opera
  • Safari
  • UCBrowser

getBrowser = () => {
    const userAgent = navigator.userAgent;
    let browser = "unkown";
    // Detect browser name
    browser = (/ucbrowser/i).test(userAgent) ? 'UCBrowser' : browser;
    browser = (/edg/i).test(userAgent) ? 'Edge' : browser;
    browser = (/googlebot/i).test(userAgent) ? 'GoogleBot' : browser;
    browser = (/chromium/i).test(userAgent) ? 'Chromium' : browser;
    browser = (/firefox|fxios/i).test(userAgent) && !(/seamonkey/i).test(userAgent) ? 'Firefox' : browser;
    browser = (/; msie|trident/i).test(userAgent) && !(/ucbrowser/i).test(userAgent) ? 'IE' : browser;
    browser = (/chrome|crios/i).test(userAgent) && !(/opr|opera|chromium|edg|ucbrowser|googlebot/i).test(userAgent) ? 'Chrome' : browser;;
    browser = (/safari/i).test(userAgent) && !(/chromium|edg|ucbrowser|chrome|crios|opr|opera|fxios|firefox/i).test(userAgent) ? 'Safari' : browser;
    browser = (/opr|opera/i).test(userAgent) ? 'Opera' : browser;

    // detect browser version
    switch (browser) {
        case 'UCBrowser': return `${browser}/${browserVersion(userAgent,/(ucbrowser)\/([\d\.]+)/i)}`;
        case 'Edge': return `${browser}/${browserVersion(userAgent,/(edge|edga|edgios|edg)\/([\d\.]+)/i)}`;
        case 'GoogleBot': return `${browser}/${browserVersion(userAgent,/(googlebot)\/([\d\.]+)/i)}`;
        case 'Chromium': return `${browser}/${browserVersion(userAgent,/(chromium)\/([\d\.]+)/i)}`;
        case 'Firefox': return `${browser}/${browserVersion(userAgent,/(firefox|fxios)\/([\d\.]+)/i)}`;
        case 'Chrome': return `${browser}/${browserVersion(userAgent,/(chrome|crios)\/([\d\.]+)/i)}`;
        case 'Safari': return `${browser}/${browserVersion(userAgent,/(safari)\/([\d\.]+)/i)}`;
        case 'Opera': return `${browser}/${browserVersion(userAgent,/(opera|opr)\/([\d\.]+)/i)}`;
        case 'IE': const version = browserVersion(userAgent,/(trident)\/([\d\.]+)/i);
            // IE version is mapped using trident version 
            // IE/8.0 = Trident/4.0, IE/9.0 = Trident/5.0
            return version ? `${browser}/${parseFloat(version) + 4.0}` : `${browser}/7.0`;
        default: return `unknown/0.0.0.0`;
    }
}

browserVersion = (userAgent,regex) => {
    return userAgent.match(regex) ? userAgent.match(regex)[2] : null;
}

console.log(getBrowser());

You can use Detect-browser.js, JavaScript library that detects and prints an object of browser information including browser language/name, user agent, device type, user OS, referer, online/0ffline, user timezone, screen resolution, and cookie enabled.

Get it from here detect-browser.js

it will give you something like that:

Here are several prominent libraries that handle browser detection as of Dec 2019.

Bowser by lancedikson - 4,065★s - Last updated Oct 2, 2019 - 4.8KB

var result = bowser.getParser(window.navigator.userAgent);

We can use below util methods

utils.isIE = function () {
        var ver = navigator.userAgent;
        return ver.indexOf("MSIE") !== -1 || ver.indexOf("Trident") !== -1; // need to check for Trident for IE11
    };

    utils.isIE32 = function () {
        return (utils.isIE() && navigator.appVersion.indexOf('Win64') === -1);
    };

    utils.isChrome = function () {
        return (window.chrome);
    };

    utils.isFF64 = function () {
        var agent = navigator.userAgent;
        return (agent.indexOf('Win64') >= 0 && agent.indexOf('Firefox') >= 0);
    };

    utils.isFirefox = function () {
        return (navigator.userAgent.toLowerCase().indexOf('firefox') > -1);
    };

Detecting Browsers on Desktop and Mobile : Edge, Opera, Chrome, Safari, Firefox, IE

I did some changes in @nimesh code now it is working for Edge also, and Opera issue fixed:

function getBrowserName() {

    if ( navigator.userAgent.indexOf("Edge") > -1 && navigator.appVersion.indexOf('Edge') > -1 ) {
        return 'Edge';
    }
    else if( navigator.userAgent.indexOf("Opera") != -1 || navigator.userAgent.indexOf('OPR') != -1 )
    {
        return 'Opera';
    }
    else if( navigator.userAgent.indexOf("Chrome") != -1 )
    {
        return 'Chrome';
    }
    else if( navigator.userAgent.indexOf("Safari") != -1)
    {
        return 'Safari';
    }
    else if( navigator.userAgent.indexOf("Firefox") != -1 ) 
    {
        return 'Firefox';
    }
    else if( ( navigator.userAgent.indexOf("MSIE") != -1 ) || (!!document.documentMode == true ) ) //IF IE > 10
    {
        return 'IE';
    }  
    else 
    {
        return 'unknown';
    }
}

If you need to know what is the numeric version of some particular browser you can use the following snippet. Currently it will tell you the version of Chrome/Chromium/Firefox:

var match = $window.navigator.userAgent.match(/(?:Chrom(?:e|ium)|Firefox)\/([0-9]+)\./);
var ver = match ? parseInt(match[1], 10) : 0;

You can use try and catch to use the different browser error messages. IE and edge were mixed up, but I used the duck typing from Rob W (based on this project here: https://www.khanacademy.org/computer-programming/i-have-opera/2395080328).

var getBrowser = function() {        
    try {
        var e;
        var f = e.width;
    } catch(e) {
        var err = e.toString();

        if(err.indexOf("not an object") !== -1) {
            return "safari";
        } else if(err.indexOf("Cannot read") !== -1) {
            return "chrome";
        } else if(err.indexOf("e is undefined") !== -1) {
            return "firefox";
        } else if(err.indexOf("Unable to get property 'width' of undefined or null reference") !== -1) {
            if(!(false || !!document.documentMode) && !!window.StyleMedia) {
                return "edge";
            } else {
                return "IE";
            }
        } else if(err.indexOf("cannot convert e into object") !== -1) {
            return "opera";
        } else {
            return undefined;
        }
    }
};

Here you find out which browser is it running.

function isValidBrowser(navigator){

            var isChrome =  navigator.indexOf('chrome'),
            isFireFox= navigator.indexOf('firefox'),
            isIE = navigator.indexOf('trident') ,
            isValidChromeVer = parseInt(navigator.substring(isChrome+7, isChrome+8)) >= 4,
            isValidFireForVer = parseInt(navigator.substring(isFireFox+8, isFireFox+9)) >= 3,
            isValidIEVer = parseInt(navigator.substring(isIE+8, isIE+9)) >= 7;

            if((isChrome > -1 && isValidChromeVer){ console.log("Chrome Browser")}

            if(isFireFox > -1 && isValidFireForVer){ console.log("FireFox  Browser")}

            if(isIE > -1 && isValidIEVer)){ console.log("IE Browser")}


        }

In case anyone finds this useful, I've made Rob W's answer into a function that returns the browser string rather than having multiple variables floating about. Since the browser also can't really change without loading all over again, I've made it cache the result to prevent it from needing to work it out the next time the function is called.

/**
 * Gets the browser name or returns an empty string if unknown. 
 * This function also caches the result to provide for any 
 * future calls this function has.
 *
 * @returns {string}
 */
var browser = function() {
    // Return cached result if avalible, else get result then cache it.
    if (browser.prototype._cachedResult)
        return browser.prototype._cachedResult;

    // Opera 8.0+
    var isOpera = (!!window.opr && !!opr.addons) || !!window.opera || navigator.userAgent.indexOf(' OPR/') >= 0;

    // Firefox 1.0+
    var isFirefox = typeof InstallTrigger !== 'undefined';

    // Safari 3.0+ "[object HTMLElementConstructor]" 
    var isSafari = /constructor/i.test(window.HTMLElement) || (function (p) { return p.toString() === "[object SafariRemoteNotification]"; })(!window['safari'] || safari.pushNotification);

    // Internet Explorer 6-11
    var isIE = /*@cc_on!@*/false || !!document.documentMode;

    // Edge 20+
    var isEdge = !isIE && !!window.StyleMedia;

    // Chrome 1+
    var isChrome = !!window.chrome && !!window.chrome.webstore;

    // Blink engine detection
    var isBlink = (isChrome || isOpera) && !!window.CSS;

    return browser.prototype._cachedResult =
        isOpera ? 'Opera' :
        isFirefox ? 'Firefox' :
        isSafari ? 'Safari' :
        isChrome ? 'Chrome' :
        isIE ? 'IE' :
        isEdge ? 'Edge' :
        isBlink ? 'Blink' :
        "Don't know";
};

console.log(browser());

Simple, single line of JavaScript code will give you the name of browser:

function GetBrowser()
{
    return  navigator ? navigator.userAgent.toLowerCase() : "other";
}

There is also a less "hacky" method which works for all popular browsers. Google has included a browser-check in their Closure Library. In particular, have a look at goog.userAgent and goog.userAgent.product. In this way, you are also up to date if something changes in the way the browsers present themselves (given that you always run the latest version of the closure compiler.)

Here's a 2016 adjusted version of Rob's answer, including Microsoft Edge and detection of Blink:

(edit: I updated Rob's answer above with this information.)

// Opera 8.0+ (UA detection to detect Blink/v8-powered Opera)
isOpera = !!window.opera || navigator.userAgent.indexOf(' OPR/') >= 0;
// Firefox 1.0+
isFirefox = typeof InstallTrigger !== 'undefined';
// Safari 3.0+
isSafari = /constructor/i.test(window.HTMLElement) || (function (p) { return p.toString() === "[object SafariRemoteNotification]"; })(!window['safari'] || safari.pushNotification);
// Internet Explorer 6-11
isIE = /*@cc_on!@*/false || !!document.documentMode;
// Edge 20+
isEdge = !isIE && !!window.StyleMedia;
// Chrome 1+
isChrome = !!window.chrome && !!window.chrome.webstore;
// Blink engine detection
isBlink = (isChrome || isOpera) && !!window.CSS;

/* Results: */
console.log("isOpera", isOpera);
console.log("isFirefox", isFirefox);
console.log("isSafari", isSafari);
console.log("isIE", isIE);
console.log("isEdge", isEdge);
console.log("isChrome", isChrome);
console.log("isBlink", isBlink);

The beauty of this approach is that it relies on browser engine properties, so it covers even derivative browsers, such as Yandex or Vivaldi, which are practically compatible with the major browsers whose engines they use. The exception is Opera, which relies on user agent sniffing, but today (i.e. ver. 15 and up) even Opera is itself only a shell for Blink.

This combines both Rob's original answer and Pilau's update for 2016 

    var isOpera = !!window.opera || navigator.userAgent.indexOf(' OPR/') >= 0;
    // Opera 8.0+ (UA detection to detect Blink/v8-powered Opera)
var isFirefox = typeof InstallTrigger !== 'undefined';   // Firefox 1.0+
var isSafari = Object.prototype.toString.call(window.HTMLElement).indexOf('Constructor') > 0;
    // At least Safari 3+: "[object HTMLElementConstructor]"
var isChrome = !!window.chrome && !isOpera;              // Chrome 1+
var isIE = /*@cc_on!@*/false || !!document.documentMode;
// Edge 20+
var isEdge = !isIE && !!window.StyleMedia;
// Chrome 1+
var output = 'Detecting browsers by ducktyping:<hr>';
output += 'isFirefox: ' + isFirefox + '<br>';
output += 'isChrome: ' + isChrome + '<br>';
output += 'isSafari: ' + isSafari + '<br>';
output += 'isOpera: ' + isOpera + '<br>';
output += 'isIE: ' + isIE + '<br>';
output += 'isIE Edge: ' + isEdge + '<br>';
document.body.innerHTML = output;

I know it may be overkill to use a lib for that, but just to enrich the thread, you could check is.js way of doing this:

is.firefox();
is.ie(6);
is.not.safari();
