If you suspect the graphics card's driver is at fault then I would try
linux-opera or even linux-firefox and see whether it also dies when you
use a drop-down menu.

Another possibility would be to set hw.physmem to say 3G or 4G in
loader.conf and see whether that affects thunderbird/firefox.  Who
knows, there may some weird problem caused by all that memory?  That
would a fairly quick and cheap way to test this.
