Mozilla has officially released the first beta test version of Firefox 3. Here’s how to try it out for yourself in Ubuntu.

  1. Download the Linux version of Firefox 3 beta 1.
  2. Extract the tar.bz2 archive that you downloaded. Simply right-click on the file and click Extract Here.
  3. Open the firefox folder that was created. Double-click on the firefox file and choose Run.
  4. Firefox 3 will start and import your settings.

Here are the changes that I ran into after playing with beta 1 for a few minutes:

I use Firefox more than any other application, and Firefox 3 looks like it will be a nice upgrade.

You may want to be careful with this though since Firefox 3 will overwrite your existing profile.

Backup ~/.mozilla/firefox/ in case you want to switch back to Firefox 2.


Remember to close Firefox before you run the Firefox file to import your settings.


Does not work for me. On my system ./firefox starts FF2 (stable version).


Make sure that Firefox 2 is closed or it will just open a new Ff2 window.


Yes, make sure FF2 is closed or if you are dumb like me will spend 30 minutes trying to figure out why FF3 will not start after you have deleted FF2…
