Is there any way to lock the toolbar?
Hello, I am wondering if there is any way to lock the toolbar so that it does not automatically pop up when you are in full screen mode and hover over the top area of the screen. I cannot easily play some browser games because they must be full screen and the toolbar popping up continuously interrupts the game.
To clarify, I do not want the toolbar to always be there; locking the toolbar so that it automatically shows when in full screen is not the solution I am looking for. I want the toolbar to disappear when I am in full screen and not popup when I hover over the top area of the screen.
Thank you for any help!

Hello. You can do that with a userChrome.css file which you have to create yourself. Remove the blank spaces in the following link. Code is provided by MrOtherGuy on git hub.

Hi, thank you for that information! I am having trouble completing this method. I can only get to the point of locating the userChrome.css file under profile>chrome, then I am lost from there. I do not understand how to add the necessary code.
You can use code in userChrome.css to hide the fullscr-toggler and prevent showing the toolbars when you move the mouse pointer to the top of the window.
*|div#fullscr-toggler {display:none!important;}
It is not that difficult to create userChrome.css if you have never used it.
The first step is to open the "Help -> Troubleshooting Information" page and find the button to access the profile folder with the random name (xxxxxxxx.default-release).
You can find the button to go to the profile folder under the "Application Basics" section as "Profile Folder -> Open Folder". If you click this button then you open the profile folder in the Windows File Explorer. You need to create a folder with the name chrome in the profile folder with the random name (name is all lowercase). In the chrome folder you need to create a plain text file with the name userChrome.css (name is case sensitive). In this userChrome.css text file you paste the text posted. On Mac you can use the TextEdit utility to create the userChrome.css file as a plain text file.
In Windows saving the file is usually the only time things get more complicated because Windows can silently add a .txt or .css file extension and you end up with a file like userChrome.css.txt or userChrome.css.css. To avoid this, you need to make sure to select "All files" in the "Save File" dialog in the text editor.
You need to close (Quit/Exit) and restart Firefox when you create or modify the userChrome.css file.
More info about userChrome.css/userContent.css in case you are not familiar:

- https://www.userchrome.org/firefox-changes-userchrome-css.html
In Firefox 69 and later you need to set this pref to true on the about:config page to enable userChrome.css and userContent.css.
- about:config => toolkit.legacyUserProfileCustomizations.stylesheets = true
