Firefox 4.0 Concept Videos Appear

In a recent blog post by Stephen Horlander, a new interface for Firefox 4.0 was shown in two concept videos that match the Ribbon style present in Windows 7. The next major overhaul of the popular browser will include a new UI developed to match the interface of the operating system that it runs on, and although Firefox 4.0 is nowhere near complete, these two concept videos provide a peek into what we may be able to expect in terms of the new design for Windows 7.

My goal was to quickly demo how this would actually look and feel because still images and wireframes can only convey so much.

The first video, which demonstrates the creation of a new tab, can be found here. A frame by frame picture is also provided:

Another, longer video is also shown that displays tab rearrangement and the “tear-off” animation.

More mockups can be found on the official wiki.
