I tried to reproduce it on two 6.1-STABLE systems but with no result,
file upload works just fine. I have a bad feeling that it's very hard
On the other hand, did the problem started to occur at a specified
date? Can you link the problem with a world / ports update?

Try to reproduce the above described behaviour and jump over with gdb.
gdb /usr/X11R6/lib/firefox/firefox-bin <pid-of-firefox-bin>
(gdb) t a a bt full
Save the output for all threads and post it on freebsd-gnome@

The above options are not the defaults for Ff, try rebuilding it using:
> My current kernel config file:
> machine i386
> cpu I686_CPU
> ident GX260
> options SCHED_ULE # ULE scheduler
Do you need SCHED_ULE? Try SCHED_4BSD instead, Ff is very picky when it
comes to threads.
