Fullscreen de Mark Tiedemann, Thor Galle

Minimalist fullscreen extension.

This extension does one thing: it adds real fullscreen functionality to every web page. Title bars will be hidden, too!

❤️ No special permissions required. No trackers, no safety risks, no bloat, no nothing. Super simple, lightweight and open-source.

Note: you may not need this extension. You can open normal full screen mode, right-click the toolbars, and click "Hide Toolbars". The extension can still be useful though in some cases, more info here.

Also available for Google Chrome and Microsoft Edge: https://chrome.google.com/webstore/detail/fullscreen/fkbigbddainndbfabdcmbhgionobgina
