I think Issue is when Jenkins try to open FireFox (It is not calling by FireFox Porfile) Not with Selenium Plug-in.
Go to Start -> Run -> firefox.exe -p -> Create FirefoxProfile. (in prefs.js file I set some Proxy details)
I am doing this because of my System / Browser has Security Policies Enabled. Due to this whenever I ran other URL, proxy pop-up comes.
For this reason I have created the FireFox Profile and the Set the proxies there. When I ran locally it is working fine. But the same script when I ran from Jenkins it is asking for pop-up.
I am sorry I have selected wrong Component. Can anyone help me in getting Right Component about FireFox?
