I use Firefox for a browser...there are better, but I like it. However about once a week...only on this site... all of a sudden my screen goes full size with the Firefox emblem saying that I need to upgrade immediately and a helpful javascript box then pops up. No way would I click on that. So I reboot and scan the computer...so far no damage. Anyone else have this happen? Guess I'll use a different browser for GoPowercat. Thanks,
