Font rendering problem in Firefox on Linux

I have this problem of font rendering/smoothing in Firefox on Fedora Linux. The fonts looked somewhat thin and not sharp. Here is the solution
Edit ~/.font.config and make sure it looks like the following

 <?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="autohint">  
   <bool>false</bool>  
  </edit>  
  </match>  
  <match target="font">  
  <edit mode="assign" name="hintstyle">  
   <const>hintslight</const>  
  </edit>  
  </match>  
  <match target="font">  
  <edit mode="assign" name="antialias">  
   <bool>true</bool>  
  </edit>  
  </match>  
 </fontconfig>
