Steps to reproduce:

The preference "gfx.prefer-mesa-llvmpipe" is never used. 
It was introduced with bug 731836 but the code which made use of it was removed with bug 958368.
Currently the only occurence of  "gfx.prefer-mesa-llvmpipe" is in source/modules/libpref/init/all.js in line 699 (see or grep/search for it yourself).

Actual results:

The preference has no impact and gives the user the impression, that he/she can influence firefox to use llvmpipe by setting it to true (which was the case but is'n anymore since bug 958368 was closed).

Expected results:

Either remove "gfx.prefer-mesa-llvmpipe" or reintroduce the code (see bug 958368) that uses this pref. 
In the first case some bugs should be closed/reopened to avoid confusion: bug 731983 (I would love to work on this addon btw), bug 958368, 731836

(Additionally I would be very glad, if someone could clarify how to officially (?) force firefox/ANGLE to use software-rendering as a fallback. I've managed to do so by (re)placing a dll (in the appropriate dir) and setting "webgl.disable-angle" and "webgl.force-enabled" to true. But this is out of the scope of this bug, I think? Thanks, though.)
