How to install Chrome Extension using Selenium & Python

Question

Hello I'm trying to install a Chrome extension with Selenium using python, I tried using ChromeDriver - WebDriver for Chrome

But it is not working, this is my code:

from selenium import webdriver
from selenium.webdriver import Chrome
from selenium.webdriver.common.by import By
from selenium.webdriver.common.keys import Keys
from selenium.webdriver.chrome.options import ChromeOptions
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.webdriver.support.expected_conditions import presence_of_element_located

import re  # regular expressions, are imported from python directly
import time
import numpy as np
import pandas as pd
import functions_database

# Pandas read CSV
df_read = pd.read_csv(
    '/home/daniel/amazon-project-scrapers/ss_scraper.edited2.csv')

amazon_data = list(df_read.amz_search)

# Chrome Driver + install plugin
ChromeOptions options = new ChromeOptions();
options.addExtensions(new File("/home/daniel/amazon-project-scrapers/chromedriver_linux64/DS-Amazon-Quick-View_v2.8.9.crx"));
ChromeDriver driver = new ChromeDriver(options);

driver = webdriver.Chrome(executable_path='/home/daniel/amazon-project-scrapers/chromedriver_linux64/chromedriver')
driver.get('https://www.amazon.com/')

And this is the error i'm getting:

File "camel_scraper.py", line 23
    ChromeOptions options = new ChromeOptions();
                        ^
SyntaxError: invalid syntax

I tried to do this in other 3 different ways, actually there is a similar question in Stack overflow whose answer is deprecated, if I find it again I'll write the link in here.

You're using the javascript syntax for setting the chromeoptions. You need to use the python syntax, as outlined on this site — G. Anderson

To add/install the DS-Amazon-Quick-View Chrome extension using Selenium's python client you can use the following solution:

Code Block:

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

  chrome_options = Options()
  chrome_options.add_extension('/home/daniel/amazon-project-scrapers/chromedriver_linux64/DS-Amazon-Quick-View_v2.8.9.crx')
  driver = webdriver.Chrome(options=chrome_options, executable_path='/path/to/chromedriver')
  driver.get('https://www.google.co.in')

For some reason it gives me this issue:

selenium.common.exceptions.WebDriverException: Message: unknown error: cannot process extension #1 from unknown error: CRX verification failed: 3

@DaniAPred That seems to be an issue with the foo.crx extension file as it can't be processed by Selenium. From Selenium's perspective this code block is proven and robust.

This code works! I found the mistake, I'll put it here because I think this 2 following steps are very important for not getting the error I had. Download extension locally. (you can use online crx-downloader, for example crx-downloader.com). (I USED ANOTHER DOWNLOADER, THIS ONE IS ACCEPTED BY GOOGLE, AND EXTENSIONS ARE UPDATED) Check version of your extension with site crx-checker.appspot.com (HERE YOU CAN VERIFY IF THE CRX IS REALLY UPDATED). If the CRX is CRX3, you will have no problems
