Install Thunderbird 3.1 Beta 2 In Ubuntu

 

thunderbird 3.1 beta 2

Mozilla Thunderbird 3.1 beta 2 was released, the new version featuring a new "Quick Filter" bar and better Thunderbird 2 upgrade/import tools (read full release notes).

I gave up installing Thunderbird from the Ubuntu official repositories or even Ubuntu PPAs a long time ago so nowadays I simply go to Help > Check for Updates to update my Thunderbird, because I installed the .tar.bz2 package downloaded from the Mozilla website. If you want to install it this version too in Linux, here's how to do it.
