Features & Capabilities

Tab Privacy-Overlay adds a local privacy-screen feature for the current tab to Firefox.

After activation via the toolbar icon, the tab behaves normally as long as the mouse pointer remains inside the browser window. As soon as the pointer leaves the window, the visible page area is covered by a local overlay page. If the corresponding option is enabled, the overlay is only hidden again once the mouse pointer has returned to the window and Ctrl is also pressed.

The overlay content is loaded exclusively locally. Instead of embedding external pages, the extension displays a Markdown page from the settings. This avoids cookie banners, embedding issues, and other side effects of external content.

Features:

Enable and disable per tab
Local overlay page based on Markdown
Edit Markdown in the settings
Import and export Markdown
Optional requirement to press Ctrl to hide the overlay
Optional best-effort pause of HTML5 videos when the overlay appears
Quick access to the settings via the right-click menu on the add-on icon

The extension stores its settings only locally in Firefox and does not transmit browsing data to external services.

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