I use both firefox and thunderbird pretty heavily on my workstation 
(14.1) and laptop (current) and have not had any issues.  a couple 
thoughts though to help you debug this:

1. maybe run a memory test and check the SMART status of your disk(s). 
i've seen behavior like this with flaky hardware in the past, and both 
of those apps are extremely memory hungry

2. are you getting core's after rebuilding debug builds?  if so what 
does backtrace show?

3. is this a low memory system?  when i was debugging a memory leak in 
firefox a while ago i wrote a wrapper that invoked it via limits(1).
