Python - Using Chrome Extensions With Selenium WebDriver

When you launch a Chrome browser from Selenium, a fresh temporary profile is created for the browser session. This means that by default, Chrome extensions are not loaded. To use an extension during a Selenium test, you must install the extension each time you launch a new browser.

Example 1: Installing a packed extension

A packed extension comes in the form of a single .crx file.

You can install a packed extension like this:

	from selenium import webdriver
	from selenium.webdriver.chrome.options import Options
	packed_extension_path = '/path/to/packed/extension.crx'
	options = Options()
	options.add_extension(packed_extension_path)
	driver = webdriver.Chrome(options=options)

Example 2: Installing an unpacked extension

An unpacked extension is a directory containing extension code.

You can install an unpacked extension like this:

	from selenium import webdriver
	from selenium.webdriver.chrome.options import Options
	unpacked_extension_path = '/path/to/unpacked/extension/'
	options = Options()
	options.add_argument('--load-extension={}'.format(unpacked_extension_path))
	driver = webdriver.Chrome(options=options)
