With Firefox releases happening more quickly, add-on developers will have less time to address compatibility issues that might surface. We’ve implemented a new compatibility process to ease that burden for the majority of add-ons.
We’ve also created a new mailing list for add-on compatibility announcements that we encourage all add-on developers to subscribe to. This is a moderated list that we’ll occasionally email with information on breaking compatibility changes and upcoming Firefox release summaries. We especially encourage developers who do not host their add-ons on AMO to subscribe, as this will be the best way to keep up with compatibility in absence of the automatic detection and bumps of other add-ons.
