Sadly, Firefox today looks like it belongs in the last decade. However, a proposed user interface evolution shows Firefox morphing into Google Chrome over two iterations.

A lot of people got excited when Mozilla announced in 2007 that Firefox 3 would include a visual refresh focussing on system integration. Finally, Firefox would look like it belonged in Windows Vista. Sadly, that wasn’t the case, and Firefox today still looks like it belongs in the last decade.

Recently, a number of blogs have picked up these screenshots, showing mock-ups of the interface for Firefox 3.7. But what I found more interesting was the proposed interface evolution shown here:

After stopping off briefly at Firefox 3.7, the interface continues its evolution until it’s practically indistinguishable from Google Chrome.

I happen to love the Chrome interface, so, if accurate, this is nothing but good news. But it’ll be a long wait until Firefox 4.0. The question now is whether Google can add support for extensions to Chrome before Mozilla adds a modern interface to Firefox.
