I post these updates every 3 weeks to inform add-on developers about the status of the review queues, add-on compatibility, and other happenings in the add-ons world.

Firefox 37 Compatibility

The Firefox 37 compatibility blog post is up. The automatic AMO validation will be run this week.

Also, if you host your add-ons outside of AMO, give this update a look. It affects the way the domain whitelist for add-on installation works.

Firefox 38 Compatibility

The Firefox 38 compatibility blog post was published yesterday. The automatic AMO validation will be run next month.

As always, we recommend that you test your add-ons on Beta and Firefox Developer Edition (formerly known as Aurora) to make sure that they continue to work correctly. End users can install the Add-on Compatibility Reporter to identify and report any add-ons that aren’t working anymore.

Extension Signing

We recently announced that we will require extensions to be signed in order for them to continue to work in release and beta versions of Firefox. If you’re an extension developer, please read the post and participate in the discussions. We will be posting a followup shortly, expanding on the reasons behind this initiative.

Electrolysis

Electrolysis, also known as e10s, is the next major compatibility change coming to Firefox. In a nutshell, Firefox will run on multiple processes now, running each content tab in a different one. This should improve responsiveness and overall stability, but it also means many add-ons will need to be updated to support this.

We will be talking more about these changes in this blog in the future. For now we recommend you start looking at the available documentation.
