Firefox is not honoring /etc/fonts/local.conf settings

Bug Description

Binary package hint: fontconfig

I have a line like this in /etc/fonts/local.conf so that all the gnome fonts below 14px are not antialiased. Strange things with dapper (breezy works) Firefox ignore local.conf and render all fonts with antialias.
Bug? Need to change something in firefox too?

<match target="font">
   <test name="size" compare="less">
   <edit name="antialias" mode="assign"><bool>false</bool></edit>

Update: firefox is totally ignoring also whatever else local.fonts directive (font-size, font-type etc). I had to manually create UserChrome.css to set the font I wish to use.

Don't understand why but <test name="size"> is ignored

changed with:

<test name="pixelsize">

Ok, I finally found a solution. I updated my XML files, please go ahead and follow this tutorial that will fix fonts for good: - Problem was in fontconfig. Now fonts in Firefox are going to look good.

Still a problem in Gutsy. (I updated last night.) I attach a screenshot, which I hope illustrates this bug (or maybe I am reporting a new bug? Let me know if that is the case). You can notice that the shapes of the letters are different in the menu bar and in the browser-rendered content. In particular, the shape of the letter ‘a’ is horrible in the latter.

In Feisty this did not seem to be the case unless certain language-support packages were installed (I cannot remember which; sorry). In Gutsy, I think I only have the support for the English-language installed; even then, this is still a problem.

I should add that this is a problem when I am using the typeface Gentium. When I use a typeface such as FreeSerif, there seems to be antialiasing (no problem; I attach screenshot for this).

The setting in my NFS-mounted home directory worked beautifully with the correct rendering in Feisty, but not in Gutsy.

Disabling language-selector.conf in /etc/fonts doesn't help?
mv /etc/fonts/language-selector.conf /etc/fonts/language-selector.conf~

Now, I have upgraded the NFS-mounted version to So both copies are, but the NFS-mounted one does not have the font problem, whereas the local one in /usr/bin/firefox does! What could be wrong?

Strangely, if I open a web link from the ‘About Ubuntu’ help page, the font is antialiased. Running
  ps -elf |grep firefox
gave the following:

Trying to mimic these commands gave Firefox instances without antialiasing. I am puzzled.

Is this an issue with the firefox-3.0 package available in gutsy universe? Anyone can verify?

to verify: Install the firefox-3.0 package. you should be able to use it without interfering your "normal" firefox install.

I installed and tested firefox-3.0. I can see the rendering is ‘different’ but the problem still persists.

In about:config, I have:

and the rendering is very similar to that in the first image I posted on 2007-10-18.

To demonstrate, I attach an image. Notice the difference in the rendering of the letter ‘a’ for example. In the image, you can see how differently gnome-panel, 2.3, Firefox, and Gran Paradiso (firefox-3.0) render the typeface Gentium with about the same size. is the best, then gnome-panel, then the Firefox versions.

Strange: I went to Preferences: Appearances: Fonts, and went into Details to turn Smoothing to Greyscale and Hinting to Slight, and the typefaces looked better (like that in! I consider it resolved this way for me.
