Introduce Local Profile Locking, a Seamless Guest Profile, and Master Password Protection

[neonx]

Hi Mozilla Team,

I would like to suggest three features to drastically improve privacy for users who share their computers with family or friends:

1. Local Profile Lock (Custom Password): When launching Firefox and the profile selector appears, selecting the main user's profile should prompt for a password. This should be a custom, locally created password specifically for unlocking the profile—not the Firefox Account (Sync) password. This prevents anyone from accidentally or intentionally opening the primary user's browsing session.

2. Seamless Guest Profile: Conversely, if someone chooses the "Guest" profile from the profile selector, the browser should open directly without asking for any password. This guest session should act like a fresh browser and completely restrict access to the primary user's saved passwords (sharing bookmarks is fine). This allows someone to quickly use the browser without compromising the main user's data.

3. Dedicated Firefox Master Password for Viewing Saved Passwords: Currently, viewing saved passwords often relies on the operating system's password (like the Windows PIN). However, since family members or friends usually know the shared Windows password, this doesn't provide real security. Firefox should strictly prompt for a dedicated "Firefox Master Password" whenever someone tries to view, edit, or copy saved passwords in the settings. This ensures that even if a random person has access to the PC and knows the Windows password, they cannot snoop through saved login credentials.

Thank you!

Hi Jon,

Thank you for sharing those links and the information.

For my own tracking, I would prefer to receive updates directly regarding my specific submission, rather than managing subscriptions to multiple external topics. Is there a way to keep this consolidated thread active or subscribe to a unified update tracker so I can be notified here when there is any development on these features?

Thank you for your time and assistance.
