You can view the entire Firefox GUI through the Browser Toolbox, although it's not enabled by default. To enable it, open the regular debugger tools (pressing F12 on your keyboard). On the debugger window (which usually appears on the bottom of the screen), there will be a three dot button next to the close button. Press that and select '''Settings'''. Under the '''Advanced Settings''' section, check '''Enable browser chrome and add-on debugging toolboxes''' as well as '''Enable remote debugging'''. Then you can close the regular debugger window. Now you can open the Browser Toolbox but going to the Firefox menu button, selecting '''Web Developer''' and '''Browser Toolbox'''. You can also use the keyboard shortcut Ctrl + Alt + Shift + I. This will allow you to inspect all of the Firefox GUI, the same way you would for a website. <blockquote>'''NOTE:''' You may be asked to approve an incoming connection. That's not a remote connection. That's you.</blockquote> Hope this helps.
