Can you please go to about:support and paste what the Graphics section says. The fact that it's blacklisted and you had to set webgl.force-enabled, while this setup is normally whitelisted, suggests that maybe the glxtest process correctly caught the crash.

Yeaaaaaaaahhhhhhhh! \o/

So the glxtest process successfully caught this crash. Firefox itself is protected from it unless one force-enables.

If you would like to get this further debugged in Mesa itself, feel free to file a bug at https://bugs.freedesktop.org

CC'ing Karl who's been looking at similar bugs recently. See if this is a dupe?

[Karl Tomlinson (:karlt)]

Mesa bugs already filed and linked from bug 589546.  Bug 589546 comment 52 explains why this shows up as X_FreeGC: BadGC.
