After the overhaul of Firefox(from version 4) and in sync with the faster development cycle (à la Google Chrome) Mozilla guys has removed the status bar in Firefox 4 to make make way for more screen space and also to imitate Google Chrome. Lots of existing users may be wondering where the good ol’ Status Bar has gone.
In the new Australis theme(starting from Firefox 29), the add-on toolbar (including the status-bar) was also removed. The Status Bar removal may have affected the users who are heavy users of Firefox Extensions.
