Someone is working on implementing Direct2D support in Firefox to enable full GPU acceleration, meaning tasks like rendering and scrolling on pages is entirely handled by the GPU. This is a feature already confirmed for inclusion in IE9 and it looks like it may show up in a future release of Firefox as well.
You can download a build of Firefox with support for this method of rendering here: http://www.bassified.nl/firefox-3.7a1pre.en-US.win32.d2d.2009.12.13.zip
It's still undergoing testing, so there's bound to be bugs, but so far I haven't noticed any yet. My browser is running much smoother, everything feels completely VSynced even on content heavy pages with lots of text and images. You can really notice the difference on this page when resizing images: vladimir/demos/photos.svg - people.mozilla.com
The only requirement is that you need to be running Vista or Windows 7. Also recommended is a GPU supporting Direct3D 10. More information is available here: Direct2D: Hardware Rendering a Browser Give it a try
