firefox 2.0.0.14 crashes

I dont know why but for the past week or so my FF has been cra****ng
for no apparent reason.  Mainly i've been on Myspace and Imeem, but my
internet habits havent changed so I really dont get why FF crashes.
And i mean, it crashes just from me signing into Myspace or
something.  Crashes at least 8 times a day... I usually have 2-4 tabs
open.  The majority of the cra****ng seems to occur when im on Myspace.
Anybody else have this problem?...
