If you are someone who always like to test out bleeding edge products and applications, then Firefox 3.1 is something that you definitely don’t want to miss. Not only does it comes with more improved features, it is also much faster than its predecessor and other browsers. The current version is at beta 2 and is available for download for all platforms. Even though it is not recommended to install in a production machine, it is already very stable and can be used on a daily basis.

If you want to test out Firefox 3.1 beta 2 (or other versions) on your Ubuntu, but don’t want it to mess up your existing Firefox setting, you can easily do so by creating a new profile. Here is how you can do so.
