Disable Page Visibility API is a Chrome add-on developed by Marvin Schopf. This free add-on falls under the category of Browsers and specifically the subcategory of Add-ons & Tools.

The main purpose of this add-on is to disable the Page Visibility API. By doing so, it prevents conferencing systems and other applications from tracking whether you are currently in another window or tab. This can be particularly useful for users who want to maintain their privacy and prevent video conferencing systems from detecting their presence in a specific tab.

The add-on is designed to provide a simple and effective way to disable the Page Visibility API, ensuring that your browsing activities remain private. It is worth noting that the source code of this add-on is publicly available on GitHub for those who are interested in exploring it further.

Please note that the add-on's icon is a derivative of "Expand New Tab" by Syafiqa Fickle from the Noun Project, used under the CC BY license.
