Version 0.24 doesn't work in TB 75.0b3 about mailbox-alert HOT 3 CLOSED

Yes, like most extensions, Mailbox Alert does not work with versions later than 68. Updating for later versions requires a full rewrite, as the internal API's that is used have been changed or removed completely. It is currently not even known if all functionality can be reproduced. I have been working on figuring out what can be and how to do it, but this is a lot of work, so a version that works with later thunderbird versions is quite some time away.

Forgot to close this, but if it was still in your extensions list, it should have updated by now; as of MA 0.25, it is compatible with Thunderbird 78.
