Im using Selenium by WebDriver in PHP script.
As selenium browser I have Firefox configurated on my docker container.
I need to add proxy header with some values to set proxy settings according to my expexctations same like I will do it using cURL like this:
curl --proxy-header "X-Header-Value: VALUE"
How to do it using selenium webdriver?
Note: its not just normal headers but proxy headers, adding it even manually in developer tools not works, but cURL version works great.
