Load chrome extension using selenium

Question

While running selenium, I need to load a chrome extension from the web store. In my research, I only found how to load an extension from the local machine.

Is it possible for selenium to load an extension from the Web Store?

Answer 1

I am not sure why you are particular about downloading from Webstore and then install into Chrome.

I found some steps to download chrome extensions:

-With a computer connected to the internet, install the extension from the extension page: https://chrome.google.com/webstore/detail/
-Navigate to the extension source code. In XP this is found at: C:\Documents and Settings\\Local Settings\Application Data\Google\Chrome\User Data\Default\Extensions\
-You should see a version folder (ie. "0.0.21_0"). Copy this folder and move it on the machine you want to install on.
-Open up chrome on the disconnected machine and go to Wrench -> Tools -> Extensions
-Click the + next to Developer mode to display the developer options
-Click 'Pack extension...' and choose the version folder as the root directory. Leave the private key file blank. This will create a .crx file in the version folder along with a private key as if you were the developer.

--Or--

1- Find the ID of the extension you’re interested in. When on the details page of the extension, it will be something like : bfbmjmiodbnnpllbbbfblcplfjjepjdn after https://chrome.google.com/webstore/detail/

2- Paste this into any other browser (not Chrome): https://clients2.google.com/service/update2/crx?response=redirect&x=id%3D~~~~%26uc

3- and replacing ~~~~ with the extension ID. You’ll be prompted to save a CRX file. Drag this file to a Chrome window and proceed with installation.

Finally, use the downloaded .crx file in ChromeOptions to load the extension

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

I did this with Python in case anyone was looking.

All you have to do is download the .crx file (I used https://chrome-extension-downloader.com/) and save it somewhere that Python can access it. In my example, I imported it to the same folder as my Python script, to load exampleOfExtensionDownloadedToFolder.crx.

from selenium import webdriver  from selenium.webdriver.chrome.options import Options   options = webdriver.ChromeOptions() options.add_extension('./exampleOfExtensionDownloadedToFolder.crx') driver = webdriver.Chrome(options=options)  driver.get('http://www.google.com')
