Does anyone know if mozbackup works with windows 10?
The website dosen't mention it as far as I can tell.
--EDIT--
For anyone googling this in the future:
Just copy the profile folder in \AppData\Roaming\Thunderbird, and merge that with the new profile folder of your new Thunderbird install
Well... It hasn't been updated in 3 years, its not surprising it doesnt mention windows 10. That and you dont need it. You literally need to copy one folder.
Here's the instructions from Mozilla https://support.mozilla.org/en-US/kb/back-and-restore-information-firefox-profiles
I'm trying to back up a thunderbird setup with all email, folders and contacts.
