It was only back in January that Firefox 10 was officially launched; it’s now March, so it must be time for Firefox 11. At this rate of acceleration, we’ll be at Firefox 100 by the year’s end!
On the user side, Firefox 11 now comes with Add-on Sync, which pretty much does what it says on the tin; you’ve now got the option to synchronise add-ons between computers at will. On the developer side, Firefox’s key new selling point is Tilt, a WebGL-based view that allows developers to see distinct page elements in a 3D style.
