FF crashes Xorg mouse still moves Maveric

[Kangarooo]

on 10.04 i had this crash. https://bugs.launchpad.net/ubuntu/+s...rs/+bug/587710 since no response im now reinstalled 10.10 to test if no xorg crashes..
im actually having now different crash.. all screen freezes and network also. mouse still moves. with raw mode i can open tty6 (still not showing in screen) and making ctrl+alt+del restart.. what dbg i should install? i have nVidia Corporation NV34 [GeForce FX 5500] (rev a1) but restricted driver i removed couse that makes screen respond slow.. so restricted not installed.

happens when in FF opening YT video (not all but most makes this crash) or http://en.wikipedia.org/wiki/Ubuntu_...)#cite_note-11 if i open without citenote then it doesnt hang. opening cite note makes screen go to cite note and its marked blue till blue fades out..
what should i install to debug X and post report couse i cant get any crash report when crashes happen. for FF ive found firefox-gdb and its installed but for X?

for now i did gdb -p $(pidof firefox-bin) -batch -ex 'handle all nostop' -ex 'handle all pass' -ex 'handle 11 stop' -ex 'cont' -ex 'bt full' -ex 'cont' > /opt/ffcrash.txt 2>&1
and
gdb -p $(pidof X) -batch -ex 'handle all nostop' -ex 'handle all pass' -ex 'handle 11 stop' -ex 'cont' -ex 'bt full' -ex 'cont' > /opt/xservercrash.txt 2>&1


heres they outputs:

1st i run only about X and when opened wikipedia link this was output after restart.

p.s. when running theese then i can even open one YT video and that Wiki link and only later crash hapens. without gdb running this happens immidiattly.
