Fix Fonts in Firefox 3.5 and Ubuntu

Fix 1: Create a new file in your home folder called ".fonts.conf" (notice the dot in front of fonts) and paste this inside the file:

<?xml version="1.0"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
<match target="font" >
<edit mode="assign" name="rgba" >
<const>rgb</const>
</edit>
</match>
<match target="font" >
<edit mode="assign" name="hinting" >
<bool>true</bool>
</edit>
</match>
<match target="font" >
<edit mode="assign" name="hintstyle" >
<const>hintfull</const>
</edit>
</match>
<match target="font" >
<edit mode="assign" name="antialias" >
<bool>true</bool>
</edit>
</match>
</fontconfig>

After this, don't forget to restart Firefox 3.5


Fix 2: Paste this in a terminal:

sudo rm /etc/fonts/conf.d/10*
sudo dpkg-reconfigure fontconfig

Restart Firefox 3.5 and it's done.

Also, I suggest you use Swiftfox which is an improved Firefox build. It doesn't seem to have any problems with the subpixel smoothing.
