which seem to cause the hang. This would be the things you see and list is a sequence of actions you do just '''before''' you shut down, plus the things you see. You may need to experiment and test to find steps that seem reliable. But if If you can't seem to find a unique set of steps, don't let that stop you from looking at the bug list (below) or filing a bug report, because the environment information you have collected from the list above be may be sufficient enough to identify the causematch with someone else's report.

'''Obtain a hang stacktrace''' - If you can, please get a stacktrace using _'''hang'''_ instructions in these references, then attach stacktrace file to a bug report. Anywhere you see "Firefox" in the instructions, please substitute "Thunderbird".
* Windows: [https://developer.mozilla.org/en/How_to_get_a_stacktrace_with_WinDbg] and use "'''!analyze -v -hang''' " instead of !analyze -v -f
