I noticed that Firefox recently gave the escape key the ability to bring the current browser window out of full screen on Mac. I use the escape key to exit out of all kinds of menus as I browse the web, and it's rather annoying when instead it takes me out of full screen. Any work arounds? Thank you!

Leaving full screen mode via ESC appears to be a Mac feature added in 92 (#1688584) and was disabled for 93 by adding the browser.fullscreen.exit_on_escape pref (#1726810;false) and got enabled again in 94 (#1732367;true).

You can check browser.fullscreen.exit_on_escape on the about:config page and set its value to false.

  • about:config => browser.fullscreen.exit_on_escape = false

You can open the about:config page via the location/address bar. You can click the button to "Accept the Risk and Continue".

DISCLAIMER: modifying prefs directly via the about:config page is not officially supported and there is no guarantee that this will keep working in future releases or otherwise "breaks" Firefox.
