Firefox asks for master password on startup

Posted

For the last few months (starting with an upgrade to new version), Firefox has asked for my master password immediately upon startup (or as soon as startup is complete), regardless of what web page I am viewing. This does not seem right; it should prompt for master password only when a site that I visit requires a site password.

Another recent post on the support forums advises going to security settings, and disabling the option for "use master password." That's not right, either.

If you use Sync then you can see the email address used for the Firefox account at the top of the "3-bar" Firefox menu button drop-down list.

This could possibly also happen if the startup page(s) include a page you have saved a login username and password.

Are you reopening pages from the previous session (Restore Previous Session)?

Are you using Sync?

Sync stores its credentials in the Password Manager and you need to enter the master password to make it possible for Sync to login.

As far as I know, I'm not using Sync.

I think cor-el has the right explanation. Although I don't use Sync, I do save pages from the previous session, and my firefox user name appears on the "3-bar" menu (thanks, I was wondering what that thing is called).

So, I just visited every tab (every saved page) in my browser, and none of them are prompting me for a site login. So, firefox should not be asking for my master password at startup time (and it frequently, but not always does). It is a security risk to unlock the password vault when it isn't necessary.

Yes, I can just "cancel" the prompt for master password, but I shouldn't have to.

You say that you see an email address in the "3-bar" Firefox menu button drop-down list.

Did you check "Options/Preferences -> Firefox Account"?

Okay, I looked under "Options -> Firefox Account." I'm not sure what I should change there. I have only one connected device (my Windows 7 computer), and the following items are checked under Sync Settings: bookmarks open tabs logins add-ons options

If you use and want to continue using Sync then you will have to accept that Firefox will ask for the master password on each startup. Note that Sync isn't meant to be used as a backup, so if you only have this single device then you can consider to stop using Sync.

Thanks, I never really intended to use Sync, so I will "disconnect" from Sync, and see if that resolves the problem.

Had the same issue - for me Kaspersky has included some new options under Setting=>Additional=>Network=>Mozilla Firefox and Thunderbird. The change the default Scan secure traffic from Windows cert store to Mozilla cert store and don't get the password prompt on start up. No changes made to Firefox setup!

This worked for me. Fixed the problem in FireFox AND Thunderbird. I was about to post this problem, until I saw this.
