Description

There is a pref in the advanced Firefox preferences dialog "Use hardware acceleration when available". We should look into what this actually does inside Firefox as of FF17-ESR.

It looks like this is only for using OpenGL to accelerate rendering of layers and drop shadows. It seems benign for now, as disabling it probably won't change the fingerprint of rendering in a substantial way (since you'd still be able to fingerprint how fast the unoptimized renderer performs). Also, if we're worried about performance fingerprinting, I think we want more general approach (#3059).

Retagging for ff24-esr to look at it again then.
