[Bug Fx release/beta] Addon buttons do not work with multiples windows (addon_buttons_in_overflow_menu.uc.js)

[sdavidg]

document.getElementById("unified-extensions-area") returns null when you open a new window.

This issue is about https://github.com/Aris-t2/CustomJSforFx/blob/master/scripts/addon_buttons_in_overflow_menu.uc.js

Not sure, what exactly causes this to fail, but I'm looking into to.

Current status: Nightly 113: works fine in multi-window environment Beta 112: does not work at all Release 111: works on first window only

[sdavidg]

Beta 112 works on first window if you set a delay:

setTimeout(function/(){
	let wofl = document.getElementById("widget-overflow-fixed-list");
	let uea = document.getElementById("unified-extensions-area");
	console.log(wofl, uea);
}, 1000)

I suppose the "document" is not ready when the script is executed, but uea is null on new windows.

But if you use this code

setTimeout(function() {
	var wm = Components.classes["@mozilla.org/appshell/window-mediator;1"]
				.getService(Components.interfaces.nsIWindowMediator);
	var ws = wm.getEnumerator(null);
	while(ws.hasMoreElements()) {
		let w = ws.getNext();
		let wofl = w.document.getElementById("widget-overflow-fixed-list");
		let uea = w.document.getElementById("unified-extensions-area");
		console.log("window", wofl, uea);
	}	
}, 1000);

uea is ok on first window, null on second window, but if you open a third window, is ok on first and second. uea is null on the last window

[Aris-t2]

Did some testing based on the above code. Sometimes it refuses to work on any window, sometimes it works on more then 5 windows. SetInverval is a dirty function to achieve this, but it at least offers some kind of results on beta for me.

(function() {
/*
	try {
	  document.getElementById("widget-overflow-fixed-list").appendChild(document.getElementById("unified-extensions-area"));
	} catch (e) {}
*/	
setInterval(function() {
	var wm = Components.classes["@mozilla.org/appshell/window-mediator;1"]
				.getService(Components.interfaces.nsIWindowMediator);
	var ws = wm.getEnumerator(null);
	while(ws.hasMoreElements()) {
		let w = ws.getNext();
		let wofl = w.document.getElementById("widget-overflow-fixed-list");
		let uea = w.document.getElementById("unified-extensions-area");
		//console.log("window", wofl, uea);
		
		try {
		  wofl.appendChild(uea);
		} catch (e) {}
	}	
}, 1000);

setInterval(function() {
	// style sheet
	Components.classes['@mozilla.org/content/style-sheet-service;1'].getService(Components.interfaces.nsIStyleSheetService).loadAndRegisterSheet(
	  Services.io.newURI('data:text/css;charset=utf-8,' + encodeURIComponent(`
		  #unified-extensions-area .unified-extensions-item-contents, 
		  #unified-extensions-area toolbarbutton + toolbarbutton.subviewbutton {
			display: none !important;
		  }
		  #unified-extensions-area toolbarbutton .toolbarbutton-text {
			display: flex !important;
		  }
		  #unified-extensions-area .toolbarbutton-icon {

			height: 16px !important;
		  }
		  #unified-extensions-button {

			right: 0 !important;
			opacity: 0 !important;
			z-index: -1000 !important;
		  }
	  `), null, null),
	  Components.classes['@mozilla.org/content/style-sheet-service;1'].getService(Components.interfaces.nsIStyleSheetService).AGENT_SHEET
	);
}, 1100);


}());

I'm not sure it's right to close it

[Aris-t2]

Let leave this open for now.

The original script works fine on Nightly (113) without intervals and timeouts on as many windows I open. We will see what happens once 113 will be on release channel.

Well, it works. Though this way it's little different from unified menu. (It lacks some features compared to it, on the other hand it's not cluttered with disabled items.) I either have clutter of unwanted icons in the overflow menu, or on the toolbar. I can't remove unwanted ones to configure mode's repository of elements. It thought movability was just some attribute that may be restored/forced-on toolbar buttons.
