It says it works with Message Filters, but when i choose the 'Mailbox Alert', it is BLANK on the right side, so you cannot choose the alert.

This review is for a previous version of the add-on (0.23.1).

Yeah, that was (I hope) the last thing that broke with the big Thunderbird changes, and the hardest one to get working again. I finally found a way to fix it, and it should now work with version 0.24.
