David: Does this happen again if you use Firefox in Safe mode? This may be something to do with your Pocket add-on.

Liz, I will attempt to reproduce the error in safe mode when I get home.

Also, I have noticed over the past couple one days that this happens in Firefox 27 as well, not just Nightly.

Liz: I have not been able to reproduce the bug in Safe Mode. What follows is information from about:support. I will attempt to find which extension is causing this bug.

Okay, I believe I have found the cause of the bug! When Firefox is started with both Pocket and Greasemonkey, I am prompted for my master password twice. When Firefox is started with any one of these plugins alone, I am prompted for my master password once. When Firefox is started without either of these plugins, I am not prompted for my master password until I visit a site which has a password stored for it (eg. Twitter, Facebook etc.)

I have also encountered this bug without any extensions.
My usecase:
Latest nightly on windows 7.
Master password enabled.
Sync enabled
A homepage requesting authentication (login / password) which is stored in the password manager

A first windows prompts me for masterpassword and a second one pops a few seconds later (I only have time to type a few characters in the first one). It does not matter in which window I type the master password, it works for both (usually, I cancel the first one and type it in the second one).

It's the same in safe mode or with a new profile (only sync and this homepage with password saved).

It should only ask once for the master password.

The same behaviour is seen with the password manager of thunderbird-daily 50.0a1 (2016-06-14) with all add-ons disabled on linux. It also ”forgets“ the master password when I enter it correctly and then click on cancel in the second dialogue.  This can be confusing and annoying.

I was getting duplicate prompts until a week or two ago with Firefox Nightly, but the behavior has changed in the past week or so. I may still get duplicate prompts if I wait long enough but I haven't seen it for a few days.

There also appears to have been a change in when the password prompts appears (it shows up later), but I can't tell whether that is a Nightly change or a change in the behavior in the web sites in my pinned tabs.

There are three bugs on this issue. I'll let someone else decide which should be marked as duplicate.
