FireFox 4

[Tathrim]

I installed it 10 days ago and it kept crashing while I download torrents. Then I installed it my gf's pc (single core) few days ago and machine started coughing for some reason. While Mozilla on, PC simply responded slower whether you were surfing or just clicking on my computer. Latest IE is way better now.

Never had any problems with previous Mozilla (but few of my friends did) and it doesn't matter 'cause Google Chrome is better, more simple, faster, (not matter how fast your PC is) more stable and it doesn't annoy you with those stupid updates all the time as Mozilla does.

Chrome DOES perform faster on basic speed tests like for like, but I've always found I go back to Firefox, simply because of the extensibility of the browser is still far superior to anything else, and that's personal opinion.

Your problem may just be the age of the machine itself. Firefox has enabled hardware accelearation for the Windows Vista and 7 platforms. If your GF has a single core machine, chances are it's running Windows XP, which is the source of your problem (and was, IMO, worse than Vista, but that's another story), so I'd stick with Chrome. But XP is now 10 years old, so performace issues on the OS isn't surprising.
