Description Kami 2015-03-24 10:19:50 UTC 
When I enable layers.acceleration.force enabled on a laptop that utilize Radeon HD 6470M (HP Probook 6560b) the Firefox becomes crashy.

We need symbols for the r600_dri.so entries in the crash dumps, see bug 81680.
Comment 2 Kami 2015-03-25 09:54:07 UTC 
locate r600_dri.so
/usr/lib/i386-linux-gnu/dri/r600_dri.so
/usr/lib/x86_64-linux-gnu/dri/r600_dri.so

sudo apt-get install libgl1-mesa-dri-dbg

Looks like the same bug, which has been fixed upstream.
