Download Mozilla Firefox 29.0 Beta

As we are used to from Mozilla, the first beta release of the next version has already appeared shortly after the release of a stable version of the Firefox web browser. In version 29, which if all goes well will be available on April 29, we will see some adjustments to the user interface, which is called the Australis theme. For example, there is a new menu that gives access to the most important functions and it has been made easier to adjust the interface. Furthermore, Firefox Sync has also been overhauled and will have to be migrated to a Firefox account. Below is an incomplete overview of the improvements that we can expect in version 29.
