When I search something on google, the tab freezes there are no result. This doesn't happen all the time, usually 80% of the time. I can open a new tab and surf the web on that. This has never happened to me. It just started thursday night. I am using firefox. Someone suggested to use another web browser so I used chrome/Chromium but the same thing happened on google and this time, the whole thing froze not just the tab. Any other website I use like youtube,Quora works fine. I cleaned up all the history, cookies, temporary internet files, everything.
OS used :Ubuntu 14.04
Something like this
