I am really annoyed about these new WebExtensions because most of my Addons will not longer work with Firefox 57+. So I am glad to find this alternative. There is only one missing option which I would really be happy with: Disabling notifications. Every time I close tabs there are these popups which tell me which Cookie was automatically deleted. I don't need them. Please add a switch to turn them off. Then you will get 5 stars. :-)

Nevermind: Sometimes I am blind. :-D Here you are with 5 stars.
