Future updates beyond TB70

[pete of ebor]

Recent 'big' updates of TB eg TB 60 & TB 68 appear to have included big internal changes to TB which have in many cases 'broken' much used add-ons. I understand TB70 will also make some big changes. Is this update also likely to break many addons ? Surely this repeated 'breaking' of add-ons is diverting volunteers time away from fixing TB itself back to fixing their add-ons..

Support for legacy addons to be dropped

When tanstaafl says legacy addon in the above thread, he means a Thunderbird 68 compatible WebExtension using a manifest.json file with the legacy property. Addons in Thunderbird 60 use an install.rdf file. These addons are not WebExtensions.

I read that a legacy bootstrap addon should be fairly easy to convert to an experiment_apis addon.
