Firefox 9 for developers

Firefox 9, based on Gecko 9.0, will ship in early 2012. This article provides information about the changes in this release that will affect developers. Nightly builds of what will become Firefox 9 are currently available on the Nightly channel.

Note: Items listed here are tentatively slated for Firefox 9; however, they may be held for a future release if testing shows they're not ready by the time Firefox 9 is due to ship. Please keep an eye on this page to stay up to date on the plans for Firefox 9.

We should change this template and call the scheduled release date.
Somthing like this: "... release is planned for 2011-12-20"
