Since FF7 was released, i get really intermittent connection to the browser. That is to say, for instance, a movie stream will abruptly terminate or websites will stop loading altogether. For instance, at random intervals, i'll try to go to google.com and it'll say "connecting" as if im not connected to the internet. But I try in IE and it works just fine. Then I restart the browser by closing all windows and all is well again. What is the issue? Using Win 7.
