Binary package hint: xulrunner-1.9

I've been using Arch Linux for the last 3 months. Now, I'm back on Ubuntu because I got tired of configuring. Configuring never ends. However, for Arch Linux, I made the best Firefox 3 package ( http://aur.archlinux.org/packages.php?ID=15184 ), which includes PGO optimizations ( http://developer.mozilla.org/en/docs/Building_with_Profile-Guided_Optimization ).

The Windows version is PGO optimised. People will hate the Ubuntu version knowing that the Windows version is so much faster. The official mozilla nightlies are PGO optimised.

This was a test I did on Arch Linux, which is compiled against i686:
Firefox 3 Beta 3 on the left.
Firefox 3 Beta 4 with Profile Guided Optimisations on the right: http://www.paste2.org/p/15666

This is what I got with this build https://bugs.launchpad.net/gutsy-backports/+bug/212468

7 times slower. I'm not sure how much i686 helps. But, my i686 PGO was 3 times faster than my normal i686.

There are no regressions. It just works.
