hide the three lines button
I would like to hide the menu button located at the top right (the three lines button) or hide the access to the firefox settings (about:preferences) but I cannot find any GPO to do this. How can I hide this button?
Thanks in advance

Can you be more specific as to what your usecase is?
We don't provide a way to block all access to things on Firefox.
You'd have to use a custom userChrome.css.
