firefox keeps saying can't connect to server for every site but internet explorer can


I was using firefox before and it worked fine. But then yesterday firefox updated itself and since then it wouldn't work. its not the firwall, not a proxey problem, I had uninstalled it and reinstalled it but that didn't work either. Internet explorer still works and so does the wireless for the laptop but just for my desktop firefox doesn't work. Now everytime I open firefox or try any other site it says "can't connect to the server at ..." what do I do.

Additional System Details

Did you check your security software (firewall)?

A possible cause is security software (firewall) that blocks or restricts Firefox or the plugin-container process without informing you, possibly after detecting changes (update) to the Firefox program.

Remove all rules for Firefox from the permissions list in the firewall and let your firewall ask again for permission to get full unrestricted access to internet for Firefox and the plugin-container process.
