IMHO quite importantly, this version also includes a list of Microsoft fonts that don't render well with DirectWrite, and will switch back to GDI font rendering for those.

On my machine, this fixes the "fuzzy fonts" issue that existed since Firefox 4 if you enabled hardware acceleration.

Thanks for the information! I first noticed the improvement in Aurora and Nightly builds, and was wondering what they did to fix the problem.

Here is some more information I just found for anyone interested:

Main bug report:

https://bugzilla.mozilla.org/show_bug.cgi?id=661471

The two new preferences:

gfx.font_rendering.cleartype_params.force_gdi_classic_for_families

gfx.font_rendering.cleartype_params.force_gdi_classic_max_size

And a post talking in detail about the issue:
