The most recent Firefox 4 beta has enhanced support for hardware acceleration on Windows and Mac OS X. This release of Firefox will be faster on more webpages while at the same time being compatible with more computers.
On Windows Vista and 7, Firefox hardware accelerates web content using Microsoft’s Direct2D framework. The latest beta of Firefox fixes bugs that made Firefox stop drawing when the graphics driver restarted. It also now has a graphics “block list” that makes sure Firefox doesn’t try to use graphics drivers or chips known to cause problems.
Hardware accelerated compositing
Firefox now hardware accelerates the composition of layers on Windows XP, Vista, and 7, and Mac OS X. If you’re running Windows, Firefox uses Direct3D-accelerated layers, while on Mac OS X, it uses OpenGL for the same task. Hardware accelerating layer composition will make some sites significantly faster; you will notice faster scrolling and faster interaction with graphically-intensive web pages. Firefox also accelerates the display of HTML5 video, giving a special boost to pages that use it.
