Does not work unfortunately. I am not sure where the fault is but on a Google search this extensions comes up as a "Full screen" extension for Firefox Android. Yet the app appears to be for the PC version of Firefox. There is no way to use it on Android.

Fullscreen by Stefan VD: A Space-Saving Marvel that does more than the name implies

Fullscreen by Stefan VD is a game-changer. This extension lets you pop out browser windows without the pesky menu and toolbars, which allows me to put have multiple real-time charts and graphs on a screen. I use a multi-monitor setup and this is the only thing I've found that can do this. It's perfect for multitaskers who want to make the most of their screen space. With Fullscreen, you can enjoy a clean and efficient browsing experience, making it an essential add-on! Highly recommended!

so handy, useful tool

Extension très pratique, en tout cas bien plus que la touche F11. Le masquage de la barre d'outils et de navigation se fait automatiquement, et réapparait automatiquement en mettant le curseur tout en haut. Bravo au concepteur

Does exactly what it says, and does it really well. Works perfectly for keeping browser apps in a separate window.

On Windows, It locks task bar so when you want it to pop out you have to click home button, but major issue is that it does not make your window more compact if you are trying to use it when your window in not in a full screen.
