Exploring the Firefox interface...

Australis is no more

The toolbar and tabs design has been revamped to a more square look.

Meet the bookshelf

Bookmarks, downloads, history and other sections now belong to this new icon

Forget about XUL

Older XUL-based extensions don’t work anymore, but it shouldn’t bring much trouble.

Speedy surfing

You’ll notice how snappily your favourite web pages load and update now. Sweet!

A more classic menu

Mozilla has decided to drop its tiled menu design and get back to basics in Firefox 57. Nice job!
