Run firefox addons from command-line

I am working 508 accessible standard for a website. There are a Firefox plugin to help check on each page a website WAVE addons
I am having a crawler that walk throught all pages of the website.
Now i want to combine WAVE addons + my crawler to check website as 508 accessibility compliance automatically.

My question is how to run Firefox addons with a specific URL from command line?

Thanks for your help,
Minh

Edit 2023, workaround Block toplevel data: see further!

Run firefox extras from command-line.

You could do many complex thing from comand line as running inline javascript (I've posted a Color RGB shower using firefox 'data:text/html.. under Another approach, at bottom of answer).

Maybe this could help you:

$ firefox 'data:text/html;charset=ISO-8859-1,
<html>
<head>
<title>TEST Demo</title>
</head>
<body>
<h3 id="title">Test demo</h3>
<script language="javascript">
window.open("http://perso.f-hauri.ch/~felix/svg/dustin_w_Clock_autonom.svg","clock","toolbar=0,location=0,status=0,menubar=0,scrollbars=1,resizable=1,width=400,height=400,top=36,left=700");                                     
window.open("https://stackexchange.com/users/flair/1965184.png","netrate","toolbar=0,location=0,status=0,menubar=0,scrollbars=0,resizable=0,width=208,height=58,top=36,left=490");
var s=10;                                                                 
function cntdwn()                                          
{                                                                 
  document.getElementById("title").innerHTML="Test demo: "+s;s=s-1;
  if (0 > s)                                                      
  {                                                                      
    window.location="https://stackoverflow.com/a/13013464/1765658";
  }                                                                      
  else window.setTimeout(cntdwn,1000);
  };                                        
  window.onload=cntdwn;
 </script>
 </body>'

This could be written:

$ firefox 'data:text/html;charset=ISO-8859-1,<html><body><h3 id="title"></h3>'"$(
    cat <<eof
        <script language="javascript">
        var s=10;
        function cntdwn() {
            document.getElementById("title").innerHTML="Test demo: "+s;s=s-1;
            if (0 > s) {
                window.location="https://stackoverflow.com/a/13013464/1765658";
            }
            else window.setTimeout(cntdwn,1000);
        };
        window.onload=cntdwn;
        window.open("http://perso.f-hauri.ch/~felix/svg/dustin_w_Clock_autonom.svg","clock","toolbar=0,location=0,status=0,menubar=0,scrollbars=1,resizable=1,width=400,height=400,top=36,left=700");                                     
        window.open("https://stackexchange.com/users/flair/1965184.png","netrate","toolbar=0,location=0,status=0,menubar=0,scrollbars=0,resizable=0,width=208,height=58,top=36,left=490");
        </script>  </body>
eof
)"

Or even:

$ firefox 'data:text/html;charset=ISO-8859-1;base64,PGh0bWw+PGhlYWQ+PHRpdGxlPlRF
U1QgRGVtbzwvdGl0bGU+PC9oZWFkPjxib2R5PjxoMyBpZD0idGl0bGUiPlRlc3QgZGVtbzwvaDM+PHNj

aW5kb3cub25sb2FkPWNudGR3bjs8L3NjcmlwdD48L2JvZHk+'

(Care to split Base64 by multiple of 4 chars!)

This work same with chromium and, I believe, near every browser...

Edit 2023: workaround Block toplevel data:

For security reason, from version 57, firefox doesn't no open this kind of links anymore. Running this command line will just open a new window and put the entire data:... link into location field.

I will have to hit in the new firefox window:

  • Ctrl+l for focusing location field,
  • Return for forcing firefox to open data:... link.

Then

  • Alt+p for activating preferences button, and finally
  • p to tell firefox: we are ok to open popups.

For doing this automatically, I use xdotool (and xwininfo, under ).

( Of course, I could go to about:config, then set security.data_uri.block_toplevel_data_uri_navigations to false, but I think this is a bad idea! )

This script could comming to become usefull... Just edit 1st part for your need.

Add-ons can't be "run" (what does it mean to run Adblock from command line, for example?).

If the add-ons you're using do not support command-line params. you can write an extension that checks the command line and calls an appropriate function of the whatever other add-on you want to "run".
