Thunderbird forgetting passwords

thunderbirdAfter a simultaneous Thunderbird upgrade and profile migration from Windows to Linux the mail program permanently forgets passwords.




The setting:

  • Thunderbird 52 on Windows
  • Back up profile
  • Restore profile to Thunderbird 60 on Linux
  • Observe that all passwords to all accounts are lost even if entered again

This seems to be some incompatibility. Things that worked:

1. start thunderbird in safe mode:

thunderbird -safe-mode

That is a workaround, as it disables plugins

2. User trefoil on a forum reports that deleting the file “pkcs11.txt” in the Thunderbird profile fixes the issue. It does.
