Currently, in about:support (Firefox 30) the "Graphics" section states the following:

enter image description here Now, I know that Firefox has (for whatever reason) disabled the hardware accelerated features for Linux users. However, as stated in this site, it should be possible to force enable it. So far, I have:

  • Set layers.acceleration.force-enabled and layers.offmainthreadcomposition.enabled to true.
  • Set the environment variable MOZ_USE_OMTC=1

It doesn't work, and the hardware acceleration remains disabled. Is there another way to force-enable hardware acceleration (performance is horrible on my computer)? Or am I just doing it wrong?

There is this bug report as well: bugzilla.mozilla.org/show_bug.cgi?id=924403 . The silly thing I find with the 'force-enabled' option is that it seems to be the same as enabling it under Settings > Advanced > General. –  Wilf Jul 4 at 16:54
    
Xrender is gone on about here as well - note hardware acceleration does not always mean the results will be faster even though it sounds cooler. –  Wilf Jul 4 at 17:06

@Wilf Well on my Windows machines Firefox with hardware acceleration on performs much faster than with simple software rendering. The thing here is whether or not I can enable it just to try it out (and hope for better performance :D) –  d.free Jul 4 at 21:59
