It has happened for about a week. I run Firefox and browse websites for about 10-15 minutes then all of the tabs stop connecting to internet. I try reloading the pages but it does not work. I try closing all of the tabs and Firefox and re-run Firefox, but it still does not connect to Internet. It does not display any error messages. All it says is "connecting". While this happens, the other browser Google Chrome works. I have tried uninstalling Firefox and reinstalled it but the problem still exits.
