Add-ons Update – 2017/01

Here’s the state of the add-ons world this month.

The compatibility blog post for Firefox 51 is up, and the bulk validation was run. The blog post for 52 is also up and the bulk validation is pending.

Multiprocess Firefox is enabled for some users, and will be deployed for all users very soon. Make sure you’ve tested your add-on and either use WebExtensions or set the multiprocess compatible flag in your add-on manifest.

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.
