" [Announcement] GNotifier on Thunderbird 60 #207
Dear GNotifier's friends,
Mozilla has just released Thunderbird 60. This new release comes with many improvements and new exciting features. It is a major update that also introduces some changes in add-ons area. Those changes have negative impact on GNotifier.
Unfortunately, in current form, GNotifier can't be run on TB 60.
There are at least two major issues that I've identified:
Options panel has to be rewritten to standalone version (so called "option type 3")
TB60 doesn't support extensions written with Add-on SDK framework (so called "jetpack extensions")
Because of the above and having very limited time, I don't see any other option but to close this project. I can't continue to support GNotifier any more :-( "
