As you might be knowing, starting from version 29, Mozilla plans to ship Firefox with a new Australis UI, which is already available in the Nightly Builds of Firefox. Recently we covered how to disable Australis and restore the classic theme in Firefox. In the latest builds, Mozilla has added a native option to enable the titlebar for the Firefox window. When the titlebar is enabled, it shows the current page title and browser icon. To enable it, follow these simple steps.
How to apply skins to Firefox Australis
Australis, the new interface of the Firefox browser, is the most radical change to its UI since the release of version 4. It is less customizable, and looks completely different compared to the current stable version. While some users like it, others are not impressed by its new look and want to disable Australis in Firefox and restore the classic appearance. However, there is good news for every Firefox user: now it is possible to customize the appearance of Firefox's Australis UI and apply cool skins to the browser.
