Figure out what to do with Torbirdy vs. Thunderbird 78 ESR
Even if we manage to ship Torbirdy on Thunderbird 68 (see #16771 for details), it’s quite unlikely that it’ll still work on Thunderbird 78, so we will probably need to figure something out.
Info gleaned on Thunderbird mailing lists:
- Updating Legacy Extensions for Thunderbird 78
- Traditional add-ons (including bootstrapped ones) will no longer be supported, possibly as early as Thunderbird 72, and almost certainly in Thunderbird 78.
- addons dev matters are primarily discussed on https://thunderbird.topicbox.com/groups/addons/
- “WebExt Experiments” and “MailExtension Experiments” may go away in a few years
