How Do You Remove the ‘is now fullscreen’ Message When Making Something Fullscreen on Firefox?
To begin, you’ll first need to access Firefox’s Advanced Options page ‘aka’ the about:config page. To do this open Firefox, then type about:config into the address bar and press Enter. After you have accepted the warning prompt (only appears on your first access of about:config per browser installation) use the Search bar to search:
Full-screen-api.warning.timeout
When the entry appears, click the pencil icon (edit) to the far right of the screen. The default value will be 3000, however, changing this to 0 will completely remove the ‘is now fullscreen’ prompt. Once you’ve made the change click the Tick to save it then Restart Firefox and the message will be gone. Alternatively, you can simply reduce the amount of time it is displayed by changing the figure to a smaller amount somewhere above 0.
