I have seen similar problems with firefox on an F7 system, but not
nearly as freqently as it sounds you are having.   I also see firefox
start to use 100% of one of the CPU's.  I suspect that java applications
cause some of these problems.  One possibility is that memory leaks are
causing firefox to use up all of your swap space.

You could leave top or htop running in a window, or even a shell loop
something like this:

while true; do free;ps aux --sort -pcpu,-vsz| head -20;sleep 2; done

and see if you can find out what is going on when the system freezes.
Beyond that I think there is a way to load a debug kernel and force a
crash dump to file a bug report with (I don't remember off hand how to
do that).
