Python WebDriver Open with Chrome Extension

When using Python with Selenium, there are times when we need to use a Chrome extension to complete some tasks. In this guide, we will go over the steps needed to open a Chrome extension with a Python WebDriver.

Prerequisites

Before starting, you should have the following:

• Python 3 installed on your machine
• Selenium Python package installed
• A Chrome extension downloaded and saved on your machine

Steps

1. First, we need to import the required modules. We will be using the webdriver module to automate the Chrome browser, and the os module to set the Chrome options.

from selenium import webdriver
import os

2. Next, we need to set the Chrome options. This is where we will specify the path to our extension.

chrome_options = webdriver.ChromeOptions()
chrome_options.add_extension('/path/to/extension.crx')

Replace /path/to/extension.crx with the actual path to your Chrome extension.

3. We can now start the Chrome browser with the options we set.

driver = webdriver.Chrome(options=chrome_options)

This will open a new Chrome window with the extension loaded.

Full Example

Here is the full example code:

from selenium import webdriver
import os

chrome_options = webdriver.ChromeOptions()
chrome_options.add_extension('/path/to/extension.crx')

driver = webdriver.Chrome(options=chrome_options)

Make sure to replace /path/to/extension.crx with the actual path to your Chrome extension.

Conclusion

And there you have it! You now know how to open a Chrome extension with a Python WebDriver. This can be useful for automating tasks that require the use of a specific extension.
