Steps to reproduce:

Upgraded from Thunderbird 31.4.0 on Win 10 to 91.1.2.

Opened Thunderbird, expecting to access the existing email accounts using saved passwords. The accounts are IMAP using normal passwords.

Actual results:

Thunderbird prompts for password to get messages.

If I enter a password and tick the "Use Password Manager ..." to save it, then:

• no e-mails are downloaded
• the password is not saved
• the error console shows:

Prompter: internal dialogs not available in this context. Falling back to window prompt. 4 Prompter.jsm:1084
NS_ERROR_ABORT: User canceled master password entry 4 crypto-SDR.js:90

If I enter a password without ticking the "Use Password Manager ...", then:

• e-mails ARE downloaded
• but obviously the password is not saved
• the error console shows:

Prompter: internal dialogs not available in this context. Falling back to window prompt. Prompter.jsm:1084
NS_ERROR_NOT_AVAILABLE: ActivityManager.jsm:129

I tried deleting cert9.db and key4.db and restarting, but the same problem occurs. On the web I see suggestions to also delete logins.json and pkcs11.txt but I don't have those files in my profile directory.

Expected results:

It should allow me to download emails AND save the password for next time.

You cannot upgrade directly from such an old version. xref bug 1733131.
