Sending to this list, because I think a few people here have done some work around WebExtensions APIs and we are looking for your feedback.
Have you tried to develop a WebExtension API? If so, we’d like your feedback on our process and tooling. Could you please take a few minutes to fill out this survey:
Please note: this is about developer APIs in Firefox for WebExtensions, not building add-ons.
Thank you for your time.
