firefox crashes when i try to download [SOLVED]

[josedimas]

I've recently remerged almost all my programs because they were pretty old with emerge --update --deep world
it remerged gtk+ and firefox and since then firefox crashes when i try to download anything to my computer.
gaim is also crashing, but it doesn't crash when i do an especific action; it just stop working.
i've read some posts about mplayerplugin and this problem, but it doesn't seems to be my problem, since i don't have even installed mplayer.
i'm looking forward to get some help, it's pretty boring when this happen...
