Hi Rajat,

thank you for this clip. It works great if I create Chrome with a visible window, but if I set also co.add_argument("--headless") then I get an exception while creating Chrome driver:

unknown error: failed to wait for extension background page to load: chrome-extension://jbflbinpmhgggppkkcgkgokiankgofla/_generated_background_page.html from unknown error: page could not be found: chrome-extension://jbflbinpmhgggppkkcgkgokiankgofla/_generated_background_page.html   (Driver info: chromedriver=73.0.3683.68 (47787ec04b6e38e22703e856e101e840b65afe72),platform=Windows NT 10.0.17763 x86_64) 
  File "E:\development\IJS\EventRegistry\python\ERAnalytics\ArticleDetectAdsInBody.py", line 83, in urlTaskLoop
    chromeDriver2 = webdriver.Chrome(chrome_options=options2, executable_path="chromedriver.exe")

Any idea how to fix this?

thank you.
My moped went

Any idea how to fix this?

I am running into the same issue. Did anyone find a way around it?

I think this SO answer can help.

Is is possible to make use of multiple proxies without opening multiple chrome windows
Currently when i initialize new instance of proxy_chrome it opens up a new window

Hey there, I am newbie and I want to ask one question. is this the correct format of manifest_json = """ code """ and background_js = """code""",
I mean these consecutive double quotes are necessary? and is there any need to change other than path to chrome driver. Thanks

Is it possible to use it with socks5 proxy?

Is it possible to use it with socks5 proxy?

Hi Did you manage to get the code for Socks5 proxy with chrome . Can you share pls

@saileshkush95 you need to create the extension directory

@rajat-np. Thanks. This works!

Maybe a usefull tip for others.
I was struggling with Chrome versions getting automatically updating causing errors of non-matching chromedriver.
I found the package webdriver_manager which can handle this automatically

I replaced line
chromedriver = os.getcwd()+'/Chromedriver/chromedriver'
by

from webdriver_manager.chrome import ChromeDriverManager
chromedriver = ChromeDriverManager().install()

Hey @rajat-np, I copied every line of code exactly and for some reason, I'm still having a problem, I get no error message, but when I check the ip that the chrome is using, it's my IP instead of proxy IP, could anyone pls help me, at this point, I have no idea what to do next. Here is my code, if anyone can spot a mistake

Hi UrsaarDev, maybe too late, but the zip file is created when you run the file

This has worked great for me! Until 2025...
Any chance of "manifest_version": 3 version due to chrome disabling v2?
