Up to Firefox 27, one could start Firefox with
MOZ_ACCELERATED=1 MOZ_GLX_IGNORE_BLACKLIST=1 firefox
or you could set
layers.acceleration.force-enabled=true
in about:config. Then you could check, whether Firefox uses hw-acceleration in about:support. There should be written something like "GPU-accelerated windows 1/1 OpenGL" instead of "0/1 Basic".
Since Firefox 28, this doesn't work anymore and graphical glitches came back (see here: https://bbs.archlinux.org/viewtopic.php?id=178024)
Any ideas/hints?
EDIT: nvidia 334.21-2, linux 3.13.6-1

I do have the same. These nvidia bugs start to piss me off, if AMD open source drivers are ready enough by the time I change, my next video card may well be one of theirs. As for Firefox, I don't have any clue.

Same result here with an AMD card with OSS driver. It worked with firefox 27.0.1

I'm suffering the same issue here, using nouveau drivers.
Just to throw it out there, I'm convinced nobody packaging for arch broke anything this time , I lost this capability using aurora (installed locally from mozilla ftp) some time ago but didnt really notice/look until version 29.
Nevermind, I seem to have fixed it after some searching: http://featherweightmusings.blogspot.co … refox.html
export MOZ_USE_OMTC=1
layers.offmainthreadcomposition.enabled ==> true
Result:
GPU Accelerated Windows 1/1 OpenGL (OMTC)

WHOA, thanks, Psykorgasm! With OMTC, hardware acceleration works again and is so much faster than before!

In my case, it only work if I start firefox from commandline. I have a keyboard shortcut which executes only the command "firefox" and so does the item in the xfce main menu.
Any ideas why this is happening?

you should change the command to
env MOZ_USE_OMTC=1 firefox

Thanks! That worked.

executes only the command "firefox"
As long as your PATH includes your $HOME/bin, then can use ~/bin/firefox, e.g.:
#!/bin/sh
ionice -c2 -n0 /usr/bin/firefox "$@"
And don't forget:
chmod 700 ~/bin/firefox

Hi, I try to get this working with setting the MOZ_USE_OMTC=1 on session startup, but wether I set it in ~/.bashrc or gnome-session-properties, it never works. Do you have an idea as to why it won't work?
Thanks in advance.
[Edit] I forgot to mention that it works with launching Firefox with a command-line argument, but I want to have it working without modifying anything...

Try to place it in *profile.
Offline
~/.bashrc
That is *not* executed when running an app from a GUI menu
Sadly, all this "profile" business is not fully standardized, and differs depending on whether e.g. xorg is started from a BASH prompt (which will have run ~/.bashrc itself).
I recommend echoing to a log file, to see what happens on your system, e.g.:
echo "$(date) Running ~/.bashrc" >> $HOME/.log

In most cases, ~/.profile will do fine. To support all methods where PAM is used, you can set variables in ~/.pam_environment. In this case you won't be able to extend variables, just set whole new values.

Works with ~/.profile
Thanks a lot ;-)
