Firefox stops working from time to time displaying this error: Hmm. We’re having trouble finding that site. We can’t connect to the server at google.com. Then, after several hours, Firefox starts working again. All other browsers work all the time. The only troubleshooting clue i found is that restarting the computer solves the problem, i.e. browser works after restarting. Then stops again. I reinstalled Firefox several time. What should be my next step in finding out where the problem is? thnx
