Mozilla team made Firefox 4 available to Ubuntu community for testing.

1. Go to the mozilla-team firefox-stable personal package archive.
2. Lucid 10.10 or later: Add ppa:mozillateam/firefox-stable to your system's Software Sources.
3. Karmic 9.10: Firefox 3.6 is the latest version available; there is no Firefox 4. To get latest version of Firefox 3.6, add ppa:mozillateam/firefox-stable to your system's Software Sources.
4. Install the package for the new version of Firefox (e.g. package name is firefox)
