Comment 463 for bug 195698

I can confirm this. It annoys me every day when I start up Firefox. It's been the case for all of Firefox 3 and Firefox 2 as well, for as long as I can remember.

Entering the master password correctly on each individual prompt causes the login credentials for the respective tab (whichever it is) to fill in, and for those you cancel, they are not, so it's obviously every process for itself.

I don't know how it's implemented at the moment, but maybe it should be set up in a callback format, a little like AJAX requests. Password manager remembers whether a prompt is open, and while there's no response from the user, it queues the requests and finally calls the callback functions for each tab that was asking for credentials.
