How to set proxy authentication (user & password) using Python + Selenium
<p>I am using Firefox WebDriver in Python 2.7 with Selenium. My python program starts Firefox browser and visits different websites when I run the program. But, I need to set the proxy with authentication, so that when program visits any website, it will visit through the proxy server.</p>

<p>There are some similar questions on SO. But, there is no specific solution for Selenium Firefox WebDriver of Python.</p>
