After the update, it became unpleasant to use

I can not create a new userscript.

I need 3.17 version ！！！

Awful compatibility update policies which scared all users away to TamperMonkey with an adequate dev.

Also lacks a lot of features other (normal) script managers easily have.

Most of the userscripts on the internet won't even work on this manager due to written above.

Plus eternally bad UI nobody cares about

Don't show the icon in YouTube. I'm on Windows 10, Mozilla Firefox

Tried to use a script multiple times with no success. Installed, reinstalled, made sure javascript is enabled. Under EDIT I added each site. No luck..It is a script for Disqus that is supposed to make clicking on (show all replies) open all of them.

This is the script :
// ==UserScript==
// @name Disqus Expand Replies Firefox 0.4
// @version 0.4
// @description Expand all 'Show more replies' links when one clicked
// @author Nerf
// @match https://disqus.com/embed/comments/*
// @run-at document-start
// ==/UserScript==

window.addEventListener('mousedown', function(event) {
if (event.target.className.indexOf('show-children')>-1) {
var ar = document.querySelectorAll('a.show-children:not(.expanded)');
for (var a of ar) {
a.className += " expanded";
a.click();
}
return;
}
});

OK I tried with another script change app and it's probably nothing wrong with Greasemonkey just a script that doesn't work- but since it was the only reason I needed it I uninstalled both apps.

Completely breaks web page functionality (i.e. youtube) causing unpredictable behavior.

Manipuler Java c'est utile mais dans le même temps greasemonkey accède à une quantité de données personnelles illimitées et ça ce n'est pas acceptable.

The documentation is awful. It doesn't work and I don't understand why.

No longer works in waterfox classic. Will update this review accordingly if it starts working again.
