I leave my home computer on all day, with firefox sitting open. I'll usually have many tabs open, youtube, gmail, etc. A cable provider is my ISP.
Sometimes when I come back after a day of work I find firefox is unable to connect to any google domain, until I open chrome. I can browse reddit or wikipedia or any site that doesn't involve a google domain just fine, but once I try to perform google search, or am loading a site that connects to google for some ad data, the browser doesn't get anywhere (just waiting for some google domain).
Upon opening chrome and loading google.com, firefox is then able to load pages from google without any problem.
I am running firefox version 25. I haven't tried disabling extensions yet. What could be going wrong with firefox? Anything I could do to find out more?
