I'm running FF 1.0.3 on an SuSE 9.2 box and it keeps crashing, apparently randomly. I've not noticed any pattern relating to what i'm doing or what sites i'm visiting, nor how many tabs i've got open.
I've not noticed the problem anywhere else, and Konqueror seems to be being pretty stable.
On crashing it just exits FF and opens the error reporting log. I've had this install since early yesterday, and it's already crashed 9 times.
