Great addon and great support of the developer. This addon works as suspected. Sorry for misunderstanding the usage of this extension. Best regards

It works just fine in both browsers you mentioned, I use it myself every day. Please create an issue at https://github.com/JustOff/active-stop-button/issues or a topic at https://forum.palemoon.org/viewforum.php?f=46 and I'll try to assist you; reviews on AMO are not a suitable place for support requests.
