Features & Capabilities

Tab Privacy Lock helps you quickly protect open tabs when you step away from your computer, share your screen, or want to avoid accidental viewing.

The extension lets you lock the current tab with a local PIN. When a tab is locked, its content is replaced with a discreet local privacy screen. Entering the correct PIN restores the original page.

You can choose the interface language from the extension popup. The PIN and lock state are stored locally in your browser. Tab Privacy Lock does not collect personal data or send browsing information to external servers.

This extension is designed for quick visual privacy. It does not replace your operating system lock screen or provide encrypted session protection.

Is Tab Privacy Lock Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Tab Privacy Lock requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Tab Privacy Lock is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
