Hi, my name’s Nick and I like the new Firefox Australis user interface. There, I’ve said it. However, it seems an awful lot of you hate the new look unveiled in Firefox 29, which is why you’ll want to install the Classic Theme Restorer 1.1.8 add-on immediately.
As its title suggests, Classic Theme Restorer pretty much dumps everything Australis introduces, except the new menu accessible via the hamburger-like button on the main Firefox toolbar. In its place is the Firefox you know and love, complete with Firefox button in Windows.
