Summary

• As majority of add-ons work from one version to the next without the need for developer maintenance, Firefox will mark addons compatible with new versions of Firefox by default, except for the following:
  • All binary add-ons
  • All strict incompatible add-ons
  • All blacklisted add-ons

• The Feature is planned for Firefox 10. Implementation has started on Firefox 10

The feature can be enabled by setting the "extensions.strictCompatibility" preference to false in about:config.

Reference

• Feature wiki page - Link

• Feature implementation has started on Add-on Manager side: bug 693901,bug 693899,bug 693897.

• Two bugs are RESOLVED on AMO: 692971 692972

Status-week 11/7/2011-11/14/2011

Implementation work has started on Add-on manager side starting with the following bugs:

• Allow addons to opt-in to strict compatibility checking
• Add preference to globally (re)enable strict compatibility checks
• Support detecting binary components, and enable strict compatibility checking when found

TO DO list:

• create 75% basic functionality test cases
• run feature basic functionality test cases on all platforms (Windows XP, Windows 7, Mac OS 10.6, Ubuntu 11.10)
• run feature basic functionality test cases on Firefox 7, 8 and 9, while upgrading from each one to Nightly.
• create test cases for edge areas and different add-on states.

COMPLETED:

• created 75% basic functionality test cases
• ran created basic functionality test cases on Ubuntu 11.10, Windows XP, Windows 7 and Mac OS 10.7
• ran feature basic functionality test cases on Firefox 7, 8 and 9, while upgrading from each one to Nightly.
• created test cases for edge areas (restartless, third party addons)

Use Cases to Test

• An add-on can have different states in a Firefox version: compatible-incompatible, enabled/disabled, pending restart, updated/in need of update.
• User installs several types of add-ons on a Firefox version with one or more of the above mentioned states
• When upgrading to a new version, Firefox will automatically set his add-ons to compatible with the new Firefox version, unless the installed add-ons are binary, blacklisted or strictly set to incompatible with the Firefox version.

Edge cases

• Upgrade and verify that installed third party and restartless add-ons are default to compatible or incompatible if binary/blacklisted/strictCompatibility listed
• Upgrade and check behavior for add-ons installed on older Firefox versions (<Firefox 7)
• Upgrade from Firefox4 successively to Firefox 5,6,7,8,9 and 10 and verify that all add-ons are listed as expected.
