TabMising, the Primary Password is only intended to protect logins. There is no overall Firefox browser password.

Even if there was an overall browser access password, it would need to be a different password than the Primary Password. As plenty of people only like to unlock their passwords when they are needed (which might not be every session), and then immediately relock them afterwards.

Whereas whatever an overall password unlocks will be unlocked for every session, for the entire session.

So what you are describing is the intended and expected behaviour of the Primary Password. If you wish to make a feature request for a full browser access password, then the place to submit feature requests is here: https://connect.mozilla.org/t5/ideas/idb-p/ideas

(assuming that such a request hasn't already been made)

An outsider can easily access the browser where you are logged into your email, as well as gain access to your Firefox account management.

Are you concerned about physical access within your home or workplace? The best protection in that scenario is to lock your computer so the person would need to know your system login to access any of your applications. You can lock it by holding down the Windows key and tapping the L key.

If you are concerned about remote access while you are away from the computer, it would be best to disconnect from the internet and/or shut down the computer.

The password function only blocks access to saved passwords. In other words, the developers anticipated the possibility that someone else might use your browser. That's fine, but why isn't the protection complete? For example, I have my email login saved. In fact, this gives someone full access to your data. I have many browsers on my PC, and I use Firefox for work and personal use. Why is it not possible to block access to tabs, bookmarks, passwords, and settings in an open browser session? The simplest example is a child. For example, you need to restrict your child's use of this browser so that nothing changes there. But they can still use another browser or program.

Hi,

The people who answer questions here, for the most part, are other users volunteering their time (like me), not Mozilla employees or developers. If you want to leave feedback for developers, you can go to the Firefox Help menu and select Share ideas and feedback…. Alternatively, you can use this link. Your feedback gets collected by a team of people who read it and gather data about the most common issues.

You can also file a bug report or feature request. See File a bug report or feature request for Mozilla products for details.
