Its your comp...I mean firefox just owns. FireFox originated from Linux, it wasn't designed to mess up your comp. Get adaware personal or something and scan for spyware/adware. IE is sooo slow. Even their 'new and improved' IE7 just plainly sucks. Take my advice, I been using IE for a looong time in my past and all it brought was ---- to my comp. Heck I can't even remember the last time I used IE. Clean out your comp and then go back to firefox. Trust me, you'll love it.
Opera is the Escalade of browsers. FF is the midsize economy car that your parents bought for you that you stick a bunch of aftermarket upgrades onto, and IE is the bicycle that everyone who doesn't know better/doesn't care is riding
Opera - Jaguar Firefox - Ford Fusion IE - your tricycle yeah, do it anyway you want. anything is better than IE.
But you have to pay more in gas for your escalade and economy car. jk firefox owns Internet explorer, i love how you can have plugins on firefox
I've used Firefox, IE, Opera, Avant, and Netscape. Avant is just IE, more or less. Opera screwed up. IE completely trashed my computer (as well as my mom's old one). Netscape...we won't go there. Suffice to say you couldn't pay me to touch it with a 10 foot pole. The ONLY time I had a problem with FF is when someone was on my computer using IE and got some spyware and viruses that caused me to have to wipe my harddrive. Firefox for the win.
