Since [bug 1718629][], Firefox has tried to make the titlebar buttons (window controls) function more like native controls. In doing so, it allows the OS to draw tooltips for these buttons. So it prevents itself from showing redundant tooltips. That means we can't style the titlebar buttons' tooltips, they don't obey preferences, they disappear after 5 seconds on Windows, and they don't appear in fullscreen mode. This is mainly for Windows users, and particularly Windows 10 users, which have less useful native tooltips. But if you use Windows 11 and still want to disable native tooltips, you can change disableSnapLayouts to true in the setting below.
