Doesn't work.

But this one does:

Full Screen NO Title/URL Bar by Rahul Varale

addons.mozilla.org/en-US/firefox/addon/full-screen-no-title-url-bar/

this is best for me

ctrl shift f does nothing even after restarting firefox, IDK man i followed your provided instructions so you get a dick slap.

It needs you to set "full-screen-api.allow-trusted-requests-only" to false in about:config for it to work. But it does work, thank god. aaaaaaaaaa

Doesn't behave as one would expect, YouTube music opened the album cover in fullscreen instead of the page.

Also it seems to only work when it wants to. Keybind on YouTube music worked the first time, but after moving the window it stopped working, didn't get it to work on other sites.

Working for me, macOS Monterey. You have to click the content of the page first!

unsure about all the bad reviews, worked out of the box on macos mojave in firefox stable build

It's a little bit janky, but it does what I need it to do.
MacOS 12.5 - M2

Not working in latest (12.4) mac monterey os. Even with about:config change.

on my old mac using it for charts. perfect.

As previous reviews pointed out, you need to set 'full-screen-api.allow-trusted-requests-only' to false in about:config.

It simple doesn't work on my macbook (command+shift+F do the old same thing and ctrl+shift+F simpy does nothing)

Not working in macOS catalina, 2021/08/16, FF91,

Not working on Mac, FF 90.0b12

Not working with Mac

Does not work (anymore?) with Ctrl + Shift + F :(

Hello, is it possible to update your addon, can you make the windows task bar appear which is at the bottom also in full screen, when you hover the mouse the bar appears and disappears, like the tabs at the top .
Thank you

Bonjour, est il possible de faire un mise a jour de votre addon, pouvez vous faire apparaître la barre des taches de windows qui est en bas aussi en plein écran, au survol de la souris la barre apparait et disparait, comme les onglet en haut.
Merci

The developer should add that it needs full-screen-api.allow-trusted-requests-only to be set to "False". Anyway, thumbs up for making an addon that finally circumvents Mozilla's failing F11 handling

I love it! With THIS hint it works perfectly on my Mac: "type "about:config" in your Firefox address bar (like going to a website), click "accept the risk and continue". then search for "full-screen-api.allow-trusted-requests-only" and change it to false."
