Mozilla is developing automatic locking for desktop Firefox private windows
Mozilla is developing a feature for desktop Firefox that would automatically lock private browsing windows when Windows, macOS or other desktop systems go to sleep, start a screen saver or the user logs out. Unlocking would require operating-system authentication to help prevent others from viewing browsing content on an unattended computer.
What to know
- 01
Unlocking would require operating-system authentication, with options including Touch ID, Face ID, a PIN or a password.
- 02
Firefox for Android already offers private-tab locking, while Safari supports locked private browsing on Mac.
Why it matters
Traditional private browsing does not retain history after a session, but windows left open can still be viewed by someone with access to the computer.
