Firefox Add-on compatibility plan for addons.mozilla.org
As we near the release of Firefox 3, the AMO team would like to share the plan for supported application maxVersions for Firefox add-ons and themes. The current supported maxVersion is “3.0b5pre”.
- Once Firefox 3 Beta 5 is released, “3.0b5″ will be added to the list and in order to support nightly builds, “3.0pre” will be added to the list as well.
- Upon release of the first release candidate (RC) of Firefox 3, we will add “3.0.*” as a supported maxVersion.
- A list of supported Firefox versions is constantly maintained on AMO. As a reminder, please test your add-on, extension or theme before claiming compatibility.
Firefox 3 will use a three-part versioning system, as opposed to the four parts used in Firefox 2. In order to specify compatibility with security and stability releases, authors should use 3.0.* instead of 3.0.0.*.
A final reminder, if the only change required to make your add-on version compatible with a new Firefox release is a change in the install.rdf maxVersion, it is not necessary to upload a new version of the add-on. Simply change the maxVersion of the add-on in the addons.mozilla.org Developer Control Panel. Users will be presented with this new version as they upgrade their browsers.
