No longer works.

Won't work. [Deprecation] Listener added for a 'DOMNodeInserted' mutation event. Support for this event type has been removed, and this event will no longer be fired. See <URL> for more information. -- and even the basic JS updater of tag content won't stop updating

Does what it says.

A sane way to stop malicious websites from going rouge. Kill popups and stop misbehavior.

Perfect.

The Best... ‌‌ ‌ Thanks ‌‌ ‌

Pressing the toolbar button does nothing. I have noted no change in JavaScript behavior. It is hard to tell if anything is functioning since the icon does not change.

I was looking for a extension that stops javascript which prohibit copy or right-click action, and this extension works very nice. I think it's much better that red cross icon indicates working status (on or off).

Works great! Exactly what I need. Have to go back to rate 5 stars.
