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

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()

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

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')

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)
