How to load extension within chrome driver in selenium with python

All my efforts to open chrome browser with Browsec extension enabled are failing. Here is what i tried in last -

# Configure the necessary command-line option.
options = webdriver.ChromeOptions()
options.add_argument(r'--load- 
extension=C:\Users\lap0042\AppData\Local\Google\Chrome\User 
Data\Default\Extensions\omghfjlpggmjjaagoclmmobgdodcjboh')

# Initalize the driver with the appropriate options.
driver = webdriver.Chrome(chrome_options=options)

driver.get("http://stackoverflow.com")

This results in error "Failed to load extension from . Manifest files is missing or unreadable"

After search for this error I get that Manifest.json file should be renamed to manifest.json.txt but doing this resulted in same error.

Any help will be highly appreciated

May be I am late to the party but this may help other. None of solution above worked for me. I am using different chrome-binary path setting in my python selenium code.

Solution:

  1. Go to extensions and check the extension ID (this will be the extension dir)

  2. Now inside your chrome dir locate the "Profile" which has the extension.

  3. Go to the extensions dir and copy the folder with name equal to our Extension ID

  4. Paste the dir inside chrome-win64 binary folder (i am using windows).

  5. Add this piece of code (eg. ID):

     # Add the path to your extension
 epath = r"dknlfmjaanfblgfdfebhijalfmhmjjjo\0.4.8_0"
 options.add_argument(f"--load-extension={epath}")

if i understood correctly you're trying to load a local unpacked extension into selenium

in that case this code should work

options = options()
options.add_argument("--load-extension=" + unpackedExtensionPath)

a better option would be to pack your extension into a crx file

Simplest answer as far as I'm aware - manifest in subfolder of location you've referenced (e.g. 3.28.2_0' or whatever the latest version of extension is...)

This assumes you're using 'options.add_argument('--load-extension=')...

For options.add_extension('reference crx file .crx')

To open chrome browser with any extension you need to use the add_extension() method through an instance of chrome.options class and you can use the following solution :

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

chrome_options = Options()
chrome_options.add_extension(r'C:\path\to\extension.crx')
driver = webdriver.Chrome(chrome_options=chrome_options, executable_path=r'C:\Utility\BrowserDrivers\chromedriver.exe')
driver.get('https://www.google.co.in')
print("Page Title is : %s" %driver.title)
driver.quit()

For Python you need wright path to manifest.json file

from selenium.webdriver.chrome.options import Options
from selenium import webdriver

path = os.path.dirname(r"C:\temp\mdnleldcmiljblolnjhpnblkcekpdkpa\19.5.1.10_0\manifest.json")

options = Options()
options.add_argument(f"--load-extension={path}")
driver = webdriver.Chrome(options=options)

Use this code to fetch extensions

from selenium.webdriver.chrome.options import Options
from selenium.webdriver.common.desired_capabilities import DesiredCapabilities

ChromeOptions options = new ChromeOptions();
options.addExtensions(new File("/pathtoChromeextension.crx")); //adding 
DesiredCapabilities capabilities = new DesiredCapabilities();
capabilities.setCapability(ChromeOptions.CAPABILITY, options);
ChromeDriver driver = new ChromeDriver(capabilities);

Use below to get crx file http://crxextractor.com/ from your extension id which is omghfjlpggmjjaagoclmmobgdodcjboh
