This table is generated using a Python script: please feel free to suggest improvements!

SDK Releases and Firefox Compatibility

Each SDK is compatible with a particular range of Firefox versions: meaning that it's tested against those versions, and add-ons it produces will be marked as compatible with those versions.

The table above shows the range of Firefox versions supported by each SDK in a tooltip. This range is not fixed for a given SDK version, but changes as an SDK goes through Development and Beta states, and as the set of available Firefox versions changes.

Firefox Versions

At any time, there are four Firefox versions that matter:

  • Release
  • Beta (release+1)
  • Aurora (beta+1)
  • Development version on moz-central (aurora+1)

Every 6 weeks, a new Firefox is released, and everyone moves along:

Release     ->  X
Beta        ->  Release
Aurora      ->  Beta
Development ->  Aurora
            ->  Development

The Rapid Release Calendar shows what this looks like for the second half of 2011 and the first half of 2012, and that's the source for the Firefox compatibility information in the table above.

SDK Versions

The SDK release process mirrors that for Firefox, except that the SDK does not have separate Aurora and Beta states. So with the SDK we have three interesting versions at any given time:

  • Release
  • Beta (or Stabilization)(release+1)
  • Development version on GitHub (beta+1)

As for Firefox, every 6 weeks a new SDK is released, and everyone moves along.

Release     ->  X
Beta        ->  Release
Development ->  Beta
            ->  Development

SDK Development Version

An SDK in the Development state is compatible with all four of the current Firefox versions.

SDK Released Version

An SDK in the Release state is compatible with the Release Firefox and the Beta Firefox at the time of the SDK's release.

So: 1.4 ships on January 10th 2012. At that time, the released Firefox will be 9, and the Beta will be 10. Therefore 1.4 will support Firefoxes 9 and 10.

SDK Beta/Stabilization Version

An SDK in the Stabilization state is compatible with the same Firefox versions as it will be compatible with in Release, plus any earlier versions still in existence.

So as long as Firefox 8 is still the current Release, and Firefox 9 is the Beta, and 10 is Aurora, then SDK 1.4 in Stabilization will support 8, 9, 10.
