I am running a Windows 7 Ultimate on my Dell laptop and it works life a button on a hot plate. Default browser on this machine is a Mozilla Firefox which has nothing wrong in it. But recently I got a pop up from some website to upgrade the version of my firefox to the 4th one. I thought why not, I began installing the new version but as soon as installation got completed. I realized that it was a Firefox 4 Beta version which I don't want to use at all. I wouldn't have installed it if I was aware about beta version. Please help me!
