CloseReview for Mailbox Alert by Losmodile
Rated 5 out of 5 stars
Works well on Thunderbird 102.10. In fact only addon and settings combo that allows good end result with Message Filters so that Inbox has default sound and subfolders (where filters move less inportant bulk e-mails) are silent.
For that, sound alert should be disabled in Thunderbird settings and also no mailbox alerts directly on folders but ony in message filters the last filter is performing single action as Message Alert with sound so it triggers after inbox is cleared of lower priority e-mails. Other methods did not work because usually sound alert seems to be generated moments before filters could move the e-mails out of inbox to subfolders.
