Today I ran Update Manager on my Ubuntu 11.04 notebook and saw Firefox 5. No PPas to install, just an easy upgrade.
- From the Keyboard, press Super+a (Windows key and the letter a)
- Type in update manager in the search field and click on the icon
- You should see something about Firefox 5 with any other updates
- Install the updates and wait
With my other updates tonight, I waited about 2 minutes before I can run Firefox 5. I can only hope the Thunderbird upgrade will be as easy.
