Works for me on MacOS Firefox, make sure to use ctrl and not command!

As others have mentioned, you must go to about:config and search for 'full-screen-api.allow-trusted-requests-only' and double click to change it to false. I needed to restart Firefox afterwards, but once I did the plugin started working as advertised. Very happy with this plugin, I now no longer have migraines when working in full-screen from the constant toolbar pop-ups!

Does not work. Appears to be abandoned.

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)
