In less than 10 months the release of Firefox version 57 will make any extension type other than WebExtensions obsolete.
I am currently planning to port a complex overlay add-on, but at this point several key APIs are not yet ready and hence I am unable to port my add-on at this point.
After inititial research I am missing:
- A toolbar API
- A sidebar API
- A proxy API
Porting my add-on will easily take 2 - 3 month. Now I wonder if there is some date in time where I can expect all key API's to be ready?
Are there any transition time planned where WebExtensions are fully developed, so we have a chance to port older add-ons with all API's available?
