Firefox Developers Have Issues With Linux GPU Drivers Too
Mozilla Firefox 4.0 will feature GPU hardware acceleration using OpenGL (or Direct2D/Direct3D under Microsoft Windows) acceleration for WebGL content and even HTML5. This support is there for Windows and Mac OS X, but for Firefox 4.0 the Linux support has been disabled and WebGL is also blacklisted for most drivers. Why? It's the problematic GPU drivers, of course.
A Firefox developer has written on hacks.mozilla.org:
We tried enabling OpenGL on Linux, and discovered that most Linux drivers are so disastrously buggy (think "crash the X server at the drop of a hat, and paint incorrectly the rest of the time" buggy) that we had to disable it for now. Heck, we’re even disabling WebGL for most Linux drivers, last I checked.
It's a sad situation, but hopefully by Firefox 4.1 or another point release the open-source Linux graphics drivers will be in a better state. To see what you're missing out on, below is a video from Mozilla demonstrating hardware acceleration in Firefox 4.
