Well it works for me, just tested with native ff, linux ff and linux
opera...  (other than youtube seems to be overloaded at this time,
videos pause a lot.)

 I see you use the nvidia blob (I use radeon with xorg drivers), did
you rebuild the nvidia driver port after upgrading to 8.2?  Or maybe
this has something to do with the vdpau support that was added to
flash with the last update and that others reported as possibly not
working properly on FreeBSD...  If you did rebuild nvidia try
/compat/linux/usr/lib/ away temporarily and see if that
fixes the panics, if yes its probably an nvidia issue.  And even if
not I guess you need to collect a backtrace or at least a textdump
of the panic, see here about how to get a dump:

If the dumping/savecore/crashinfo script worked you should get a
new /var/crash/core.txt.X file with the backtrace (among other
things) after the next boot.

 Good luck, :)
