yes, this is firefox 3.0 rc1, but the problem started with 3.0 beta 5. also, perhaps it is of any help that sometimes, very rarely, it works. I suspect that it has something to do with starting firefox after an update process (of packages which are unrelated to firefox) until rebooting. But I cannot say this for sure.
