While adjusting our fixes and features to the new Thunderbird 153 code base, we painfully come across bugs that the Thunderbird folks have abandoned and where Betterbird had to come to the rescue to offer users a decent experience. Here are some of them, and yes, we mentioned them before here and here.
| Feature - Bug | Reference | Date abandoned | Comment |

| Account colours | Many, latest ticket in bug 1882368 | Miraculously showing action in May 2026 | Add-on was a Supernova 115 victim |
| Linux system tray | Latest ticked in bug 1946946 | Some recent action | They seem to be unable to push it over the finishing line |
Let's ask again (quoted from here): Where is the management who assigns a developer to get the issue fixed? Where is accountability?
Oops, looks like the Director, Desktop & Mobile Apps abandoned some of the bugs himself. Well, there you go!
