Install Thunderbird 3 on Ubuntu

Finally, Thunderbird 3 was released with many new and interesting features (read more about the new features here) but it doesn't contain .deb package for easy one click installation on Ubuntu. Well, we gonna fix that with this easy one line install tutorial:

1. open terminal and copy/paste(Shift+Ctrl+V) the next line into it:

sudo add-apt-repository ppa:ubuntu-mozilla-daily/ppa && sudo apt-get update && sudo apt-get install thunderbird-3.0

And that's it. This will update your repository, download Thunderbird 3 for you and install it while you are enjoying in a nice cup of coffee. :)
