Can you please ty the steps from: https://fedoraproject.org/wiki/How_to_debug_Firefox_problems
Thanks, that helped. I discovered that the problem is being caused by the Estonian ID (smart) card add-on. Disabling this add-on allows Firefox to start. I didn't notice in the above link how I might further debug the add-on. I don't see any new dump files anywhere.
So this obviously isn't a firefox problem - you may close this. I'll see what I can determine using gdb.
