User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.14; rv:80.0) Gecko/20100101 Firefox/80.0

Steps to reproduce:

Using Restart with Add-Ons Disabled, restart Thunderbird.

Actual results:

A couple of things, seemingly randomly:

• Before any windows are displayed, the prompt to enter the master password is displayed. Before I can enter anything, the main Thunderbird window is displayed, also with a prompt to enter the master password.
• The main Thunderbird window is displayed, the prompt to enter the master password is displayed, then another prompt to enter the master password is displayed on top of it.

Sometimes a master password prompt will get "stuck" in the background, requiring Thunderbird to be force restarted.

Note that this is a regression. Thunderbird used to do this but it was fixed a number of major versions ago, but reappeared recently (probably in 78, maybe 78.2)

Expected results:

A single master password prompt is displayed (initially, obviously it will be redisplayed if the wrong master password is entered).

Brian, are you still seeing this issue?

If yes, you want bug 1685877

I'm not seeing it any more, thanks.
