Hi, I'm using Firefox 24.1.0 ESR on a Debian Jessie and hardware acceleration doesn't get enabled unless I've force it to be enabled via about:config. I use a fairly recent version of the proprietary Nvidia drivers and it doesn't seem like blacklisted (at least it wasn't on the resources I can find on the internet, I don't know how recent they are) The situation is same on both 32 bit and 64 bit builds of vanilla Firefox from Mozilla or Iceweasel from Debian. I've created a new profile but it didn't change the situation. I've added the troubleshooting details of the new profile below. Anybody know * if this version of the Nvidia driver is blacklisted or not, * where can I access the up-to-date blacklist * Is there some other problem than blacklisting causes this issue? Thanks.
