It has been out for awhile, but it seems like a lot of people weren't aware of the feature. One additional usage - introduce non-programmers/web designers to what is really behind what they see on a webpage. Most people find the 3D view pretty cool, no matter if they're a technical person or not. It's also been great to see the FF developer tools improve so much recently.

"This content covers features introduced in Firefox 11"
We're now on Firefox 14. It's reasonably old.

Of course, Firefox 11 was less than 6 months ago.
It was an add-on ("Tilt" iirc) before that too.
