Browser crashing and Error massage

sometimes my browser runs into this

and then it opens up one new window and nothing is clickable on the internet and I'm forced to restart my computer.it all started after my NO$GBA crashed and did some odd thing to my webpage and closed it.I know IE sucks ass, but I never had this problem before.EDITED
I mostly get this after having more then three pages open or when on some site such as Youtube or with lots and lots of adds

Um... IE gets about 16/100 on the Acid3 test. My DSi gets 59/100.
My DSi is more standards complient than Internet Exploder.
I'd ditch IE. Firefox is faster and works better.

Acid test? and i'm thinking about ditching it, but doesnt it take a mess load of space?

What, firefox? Only a few megabytes.

I get 93/100 on FireFox.

Or google chrome, faster than firefox and 100/100 on acid test.If you want more info on the test click on the Big A

if you're on a not so powerful computer with limited resources then use chrome, if you're on a bit of a faster computer then there's no reason not to be using firefox over IE
