	/*
	Adds a new toolbar button that 1) opens the content toolbox on left click; 2) opens the browser toolbox on right click; 3) toggles "Popup Auto-Hide" on middle click. Left click will open the toolbox for the active tab, or close it if it's already open. Right click will open the elevated browser toolbox if it's not already open. If it is already open, then instead of trying to start a new process and spawning an irritating dialog, it'll just show a brief notification saying the toolbox is already open. The button also shows a badge while a toolbox window is open. Middle click will toggle the preference for popup auto-hide: `ui.popup.disable_autohide`. This does the same thing as the "Disable Popup Auto-Hide" option in the menu at the top right of the browser toolbox, prevents popups from closing so you can debug them.

	If you want to change which mouse buttons execute which functions, search for `userChrome.toolboxButton.mouseConfig` in <about:config>. Change the 0, 1, and 2 values. 0 = left click, 1 = middle, and 2 = right. By default, when you open a browser toolbox window, the script will disable popup auto-hide, and then re-enable it when you close the toolbox. I find that I usually want popup auto-hide disabled when I'm using the toolbox, and never want it disabled when I'm not using the toolbox, so I made it automatic, instead of having to right click and then immediately middle click every time. If you don't like this automatic feature, you can turn it off by setting `userChrome.toolboxButton.popupAutohide.toggle-on-toolbox-launch` to false in about:config.

	You can force the browser toolbox to open in multiprocess mode by holding Shift and Accel (Ctrl/Cmd) when you right click (or whatever mouse button you set `browserToolbox` to for `userChrome.toolboxButton.mouseConfig`) the button.

	When you middle click, the button will show a notification telling you the current status of popup auto-hide, e.g. "Holding popups open." This is just so that people who use the feature a lot won't lose track of whether it's on or off, and won't need to open a popup and try to close it to test it. The toolbar button also changes appearance while popup auto-hide is disabled. It becomes blue like the downloads button and the icon changes into a popup icon. This change is animated, as long as the user doesn't have reduced motion enabled. All of these notifications use the native confirmation hint custom element, since it looks nice. That's the one that appears when you save a bookmark, `#confirmation-hint`. So you can customize them with that selector.

			// Modify these strings for easy localization. I tried to use built-in strings

			// follow the standard format. It can only be parsed by the devtools' own
			// special l10n module, which itself can only be imported by a CJS module.
			// Requiring CJS just for a button seems ridiculous, plus there really aren't
			// any localized strings that work for these confirmation messages anyway, or

			// can only have one toolbox open per-window. So if I have 3 windows open, and
			// I right-click the toolbox button in window 1, then it'll launch a browser
			// toolbox for window 1. If I then right-click the toolbox button in window 2,
			// it'll launch a browser toolbox for window 2. But if I go back to window 1
			// and right-click the toolbox button a second time, it will do nothing except
			// show a brief confirmation hint to explain the lack of action.
			alreadyOpenMsg: "Browser Werkzeuge sind bereits geöffnet.",
			// Confirmation hint. This appears when you first middle-click the toolbox
			// button. It signifies that popups are being kept open. That is, "popup
			// auto-hide" has been temporarily disabled.
			holdingOpenMsg: "Popups werden offen gehalten.",

						* Shows a transient, non-interactive confirmation hint anchored to an
						* element, usually used in response to a user action to reaffirm that
						* it was successful and potentially provide extra context.
						*
						* @param  anchor (DOM node, required)
						*         The anchor for the panel. A value of null will anchor to the
						*         viewpoint (see options.x below)
						* @param  message (string, required)
						*         The message to be shown.
						* @param  options (object, optional)
						*         An object with any number of the following optional properties:
						*         - event (DOM event): The event that triggered the feedback.
						*         - hideArrow (boolean): Optionally hide the arrow.
						*         - hideCheck (boolean): Optionally hide the checkmark.
						*         - description (string): If provided, show a more detailed
						*                                 description/subtitle with the passed text.
						*         - duration (numeric): How long the hint should stick around, in
						*                               milliseconds. Default is 1500 — 1.5 seconds.
						*         - position (string): One of a number of strings representing how the anchor point of the popup
						*                              is aligned relative to the anchor point of the anchor node.
						*                              Possible values for position are:
						*                                  before_start, before_end, after_start, after_end,

						*                              For example, after_start means the anchor node's bottom left corner will
						*                              be aligned with the popup node's top left corner. overlap means their
						*                              top left corners will be lined up exactly, so they will overlap.
						*         - x (number): Horizontal offset in pixels, relative to the anchor.
						*                       If no anchor is provided, relative to the viewport.
						*         - y (number): Vertical offset in pixels, relative to the anchor. Negative
						*                       values may also be used to move to the left and upwards respectively.
						*                       Unanchored popups may be created by supplying null as the
						*                       anchor node. An unanchored popup appears at the position
						*                       specified by x and y, relative to the viewport of the document
						*                       containing the popup node. (ignoring the anchor parameter)
