crash and....

Well, I had downloaded the 0.8 Firefox browser but it still crashed last night. But, I don't think it's the fault of Firefox. Because it's the same message board that it keeps happening on. Some incompatibility maybe??
Anyway, to get my favorites back onto Firefox from the old browser - I had copy and pasted it all (didn't know of an easier way).
After the crash, all my old favorites came back onto the new Firefox. I have deleted all of the old browser but not before I downloaded Firefox.
So, does it just automatically transfer favorites on over??
I swear, sometimes I think this puter has a mind of its own.
