If you are any kind of a techie you run some pre-release software.
Since joining Mozilla I’ve been amazed at how much work gets done by such a small group of people.
One of the ways this happens is that the Open Source community helps and not just by writing code. Testing new features and filing bugs is vastly important too.
Plus, you get to use the latest and greatest features.
As a truely Open Source project, the daily build (actually the NIGHTLY builds) of Firefox are available each day.
The Mac and Windows builds give you installers but, as Linux wizzards know, Linux works a bit differently.
The easier way to do it is to open a Terminal window and use the following three separate commands.
sudo add-apt-repository ppa:ubuntu-mozilla-daily/ppa sudo apt-get update sudo apt-get install firefox-trunk
Then you can use the automatically installed launcher to run Firefox Nightly.
