Solution for Thunderbird crashes/freezes
I had a problem with Thunderbird for weeks after an upgrade from WIN 8.1 to WIN 10. The symptoms were just like those described in many posts. Thunderbirds starts normal but after clicking any button it becomes unresponsive. No error message or anything. It took usually 2 minutes before it 'cleared', was than working fine for a few minutes and bang- it happened again.
After a little research I found out that in some instances, after the WIN upgrade, multiple unnecessary 'MSF' files were in my Thunderbird profile folder. A simple free tool called Thunderfix helped me out of the misery. Now everything is fine and works as it should. I do not have any vast interest in promoting this tool or the developer, just wanted to share the solution I found. This is the link for the tool.

that "tool" simply deletes all the MSF files in your profile. Not really a tool. I would be more interested in these "multiple unnecessary 'MSF' files were in my Thunderbird profile" what extra ones did you have?
