9.10 Problem: Disable Subpixel font smoothing in Firefox?

[wisam]

Yesterday I made a fresh install of Karmic Koala. I hate Subpixel smoothing (aka ClearType). I always set the font smoothing method to Grayscale.

The problem is Firefox insists on using Subpixel smoothing in rendering pages and in the interface itself (menu bar, address bar and dialogue boxes). The big blurry thick fonts are hideous.

Gnome Help has nearly the same problem. The rendering engine also uses Subpixel smoothing.

Here's a screenshot to understand what I mean:



Notice the difference between the fonts in Gnome's panel and those of Firefox's menu bar.

Note: My problem is the opposite of this.

Any ideas?

EDIT: changed title to clarify that the problem is that of font hinting and not smoothing. See post below.
