Firefox 4.0 Beta 5 Font Rendering

If you’re running Firefox 4.0 b5 on Windows and you’ve suddenly noticed that your fonts look utterly hideous, you’re not the only one.

Direct2D & DirectWrite landed back in February, but were only turned on in nightly builds up until now. Suddenly with Beta 5, a lot of users, myself included, are noticing that their fonts look vomit-inducingly bad. Hardware acceleration is to blame.

If you have this problem, here’s a fix:

  • Go into about:config
  • Find mozilla.widget.render-mode
  • Change the value from -1 to 0
  • Restart Firefox

VoilĂ , problem solved! Be sure to report that you have the issue in the Firefox feedback links.
