Sometimes, when loading a website, the browser freezes. Then the computer locks up and I have to use the power button to turn it off. There seems to be no pattern to this problem. I'm also not sure whether or not the problem begins within Firefox, but a web page was loading every time it happened. It has only started happening this week.

Same for me on Vista. I was not able to spot the issue origin but I think it's related to ZoneAlarm ForceField firewall and Firefox 3.6 couple

Just downloaded and installed Firefox 4.0 on Windows 7. When I went to the "About Us" link, my cursor froze. The CPU was also working overtime. Had to restart the computer. Tried again, and same thing happened on the "About us". Never had the cursor freeze before installing Firefox. So uninstalled and will wait for a fix, but looks as though this is a chronic problem...

I seem to be having a very similar, if not exactly the same issue. I'm using the latest production FF 11.0 release on Win7 64 and as with this not only does FF freeze, but I can't task switch, or anything. The one thing I've noticed is that when the lockup happens, it always appears to be loading some custom font from a CDN, if I breathe deeply and slowly and allow the request to complete everything seems to eventually unfreeze and I can continue, so maybe something to do with implementation of custom font loading?
