    Possible Thunderbird glitch that MAY affect users.

    Just updated Thunderbird to 38.3, restarted and it was basically unusable, no emails visible etc.

    The fix.

    Clear the browser cache Menu Bar\Tools\Clear recent history and the Windows Temp directory.
    Shutdown any anti-virus software you are running. (optional, I never)
    Download a new copy of the full installer from
    Delete the directory C:\Program Files (x86)\Mozilla Thunderbird
    Run the installer.
    Restart the anti-virus program. (if needed)

    Yes, good advice.:)
    That is the standard procedure for a broken TB install, though it is rarely needed (regardless of Window OS flavor or TB version). (I've never had to do it in >12 years of using TB.)
    And AFAIK there is nothing "special" about TB 38.3.0 that ought to break upon upgrading.

    Having said that, it's generally a good idea to backup one's TB profile (aka user data) before doing a reinstall, using Mozbackup or some other means.

    One's stuff (including all of one's email messages, account data, etc.) should not be affected by a program reinstall.
    But, having a profile backup "just in case" is not a bad idea.

    Another tip for a trouble-free upgrade: rather than using the program's auto-updater, download the full TB installer from HERE. It can generally be run on top of an existing installation. Doing so seems overall to be a bit more reliable than the auto-updater.

I can see where one can choose which email client to use as the default in the system settings, but Thunderbird is not listed in the available options.

Mozbackup still works fine under W10. A Thunderbird backup may take a while depending on its size. Mine was 2.1GB I back mine up monthly to an external drive and NAS just in case ;)
