Compatibility Communications

Most of you should have received an email from us about the future compatibility of your add-ons. You can use the compatibility tool to enter your add-on ID and get some info on what we think is the best path forward for your add-on. This tool only works for listed add-ons.

To ensure long-term compatibility, we suggest you start looking into WebExtensions, or use the Add-ons SDK and try to stick to the high-level APIs. There are many XUL add-ons that require APIs that aren’t available in either of these options, which is why we ran a survey so we know which APIs we should look into adding to WebExtensions. You can read about the survey results here.

We’re holding regular office hours for Multiprocess Firefox compatibility, to help you work on your add-ons, so please drop in on Tuesdays and chat with us!

Firefox 48 Compatibility

The compatibility blog post for Firefox 48 is up, and the bulk validation will be run shortly.

As always, we recommend that you test your add-ons on Beta and Firefox Developer Edition 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

The wiki page on Extension Signing has information about the timeline, as well as responses to some frequently asked questions. The current plan is to remove the signing override preference in Firefox 48.
