unknown error: failed to wait for extension background page to load:

[triartleet]

What are you trying to achieve? (Expected behavior)

I am using Selenium with the latest Chrome driver. I want to use a proxy with authorization and considering that this behavior is not supported I am following your guide: https://github.com/RobinDev/Selenium-Chrome-HTTP-Private-Proxy

What do you get instead? (Actual behavior)

Generally, it works. After hours of work at some point I am getting the following fatal error. Please note, that I am making many plugins for different proxies without any issue.

PHP Fatal error:  Uncaught Facebook\WebDriver\Exception\UnknownServerException: unknown error: failed to wait for extension background page to load: chrome-extension://nknfhemedcefohicgiceepeoabnocgpc/_generated_background_page.html
from timeout: Timed out receiving message from renderer: 10.000
  (Driver info: chromedriver=2.33.506092 (733a02544d189eeb751fe0d7ddca79a0ee28cce4),platform=Linux 4.9.0-3-amd64 x86_64) (WARNING: The server did not provide any stacktrace information)

How could the issue be reproduced? (Steps to reproduce)

The code is pretty much the same with the "how to use it" from Selenium Chrome HTTP Private Proxy and I cannot think of any way to reproduce.

• Php-webdriver version: 1.4
• PHP version: 7.0
• Selenium server version: 3.6.0 (Latest)
• Operating system: Debian 9
• Browser used + version: Chrome v.61

I am not sure if its related to your code, (probably not) but I 'd like to hear your input.

Any solution for this @RobinDev @henices
This works perfectly for me but when running chromedriver in headless mode I am getting failed to wait for extension background page to load: chrome-extension://hgifibfnlmmjjglblhlbmpknpfndibjh/_generated_background_page.html.

This works perfectly for me too but again when running chromedriver in headless mode I am getting failed to wait for extension background page to load: chrome-extension://hgifibfnlmmjjglblhlbmpknpfndibjh/_generated_background_page.html.

Hello @RobinDev ,
Same issue The process started from chrome location /usr/bin/google-chrome is no longer running, so ChromeDriver is assuming that Chrome has crashed.

I am also facing same issue any update on this issue

Use "--headless=new" option, instead of "--headless". Then will work.
