Shutdown hangs, where Thunderbird is still running after shut down, do not all have the same cause, even if different hangs on the same OS. What To determine why it is hanging it is helpful to describe what is running in the environment, a stacktrace, and a list of steps to reproduce are all helpful in determining what kind of hang you are seeing. This may require some experimentation testing on your part, and we know this is not always possible. But providing it is important to provide as much of the needed information as you can, and state how often you see the hang (always, rarely, etc) is important. Also, answers to the following easy questions helps identify the type of hang:
# If the problem is reproducible and you have add-ons/extensions installed, does the hang happen with Thunderbird started in [https://support.mozillamessaging.com/en-US/kb/Safe+Mode safe mode]? If it can't be reproduced in safe mode then the problem could be an extension. Experiment by disabling add-ons until you find the cause, and contact the add-on author.
#* does hang happen without calendar/lightning extension? ({{Bug|532435}})
# was online or offline used, either via your explicit action, or automatically due to a dropped network connection?
More technical ... if you can, please attach:* attach stacktrace file to bug using _hang_ instructions:
