Why does firefox keep crashing on me when i have Javascript enabled?

[LW07]

Topic. I have tried several versions, 3.0.9, 3.5.1, and 3.5.3 and they all crash on me like crazy when i enable Javascript.

Anyway of fixing this WITHOUT disabling Javascript?

Does it crash on certain sites/webpages?

 

[LW07]

mainly on urbandictionary.com and on Kaspersky's free online scanner thing.

can get on them on google chrome and IE no problem

 

[LW07]

Also gives me trouble on others, tried reverting back to firefox 2 and it kept crashing even more. What gives here?

EDIT: I found out that AVG Safe Search can cause problems so i disabled it and presto! Problem solved!
