Download and Try Out the New ‘Australis UI’ Test-Build of Firefox for Windows

By Akemi Iwaya on June 21st, 2012

We have all been hearing about the upcoming changes to the UI in Firefox and now the first test build is finally available to try out. Mozilla software engineer Jared Wein has worked hard and put together an unofficial (at the moment) Australis UI build that you can download as a regular installer or as a portable in zip file format.

Here is a closer look at the new tab setup in the Australis build. Notice that only the focused tab is non-transparent while the non-active tabs blend nicely into the background.

Special Note: Our screenshots were taken in Windows 8, thus the slightly different looking (non-rounded) corners on the app window.

The test build only works on Windows at the moment, but you can bet that Linux and MacOS builds are coming in the near future!
