Firefox 4.0 Mockups

The pace at which Mozilla works can seem insane. It was less than a month ago when the the company released Firefox 3.5. Only three weeks later, Firefox posted screenshots of Firefox 3.7, which includes a change to the Tools bar and an Embracing Glass design.

But the ambition doesn’t end there. The Firefox team is looking even farther in the future: all the way to Firefox 4.0.

They’ve posted mockups of the new Firefox 4.0 design (included below) on their wiki. Firefox warns that they are just for brainstorming, but they provide the world’s first real glimpse into the next edition of the Firefox browser.
