I knows this is not one of your products, but I was hoping to get any type of advice, or maybe a suggestion where to get help.

All my current custom buttons work except for this one.

`// 'about:'-Button script for Firefox 89+ by Aris, edits by Speravir
//
// Need a different 'about' page button?
// - replace 'about:config' url with a different 'about:' url
// - replace button id
// - replace icon / icon url / icon color

(function() {

if (!window.gBrowser) return;// add. Speravir

const
buttonID = "about-addons-button",
address = "about:addons",
labelText = "About:addons Button", // button title
tooltip = "Open addons page", // tooltip content
css = // code for button icon
#${buttonID} .toolbarbutton-icon { list-style-image: url("chrome://mozapps/skin/extensions/extension.svg"); /* icon / path to icon */ fill: dimgray; /* icon color name/code */ };

try {
ChromeUtils.importESModule("resource:///modules/CustomizableUI.sys.mjs");
let sss = Components.classes["@mozilla.org/content/style-sheet-service;1"].getService(Components.interfaces.nsIStyleSheetService);

CustomizableUI.createWidget({

	let win = Components.classes["@mozilla.org/appshell/window-mediator;1"]
	.getService(Components.interfaces.nsIWindowMediator)
	.getMostRecentWindow("navigator:browser");

	if(event.button === 0) {
		try {
			win.gBrowser.selectedTab = win.gBrowser.addTrustedTab(address);
			setTimeout(function(){
				document.querySelector("#toolbar-context-menu").hidePopup();
			},0);
		} catch (e) {}
	}

	}

},
onCreated: function(button) {
	return button;
}
});

// style button icon
let uri = Services.io.newURI("data:text/css;charset=utf-8," + encodeURIComponent(css), null, null);
sss.loadAndRegisterSheet(uri, sss.AGENT_SHEET);

} catch (e) {

})();`

That's a modified Aris script.

Remove the if (!window.gBrowser) return;// add. Speravir part
