Firefox is the Culprit for Beachballs?

[IronMac]

Hi all,

My G4 933 is being beachballed to death and I only restarted the system three days ago. Seriously, it's beachballing even as I type this out. Running 10.3.9, 1 gig of ram, lots of HD space. Activity Monitor shows Page ins/outs of 315892/249942.

I strongly suspect that it's FF 2.0...latest version. If I upgrade to the 3.0 beta will it still have sessionsaver in case of a crash?

Thanks.
