I used to use NoScript religiously, but since the move to `quantum` I couldn't seem to get it to work right. Either I couldn't understand the icon system or or was buggy. Has it improved since then?
Quantum deprecated the old method of Add-On development in favor of Web Extensions. NoScript didn't have a Web Extensions version initially and has been working out the transition ever since. But that was 2 years ago...
I switched to uMatrix when NoScript wasn't working with Quantum yet. I think I like it better than NoScript now anyway, and have never gone back.
There was a hiccup during the Firefox WebExtension switch, but it has been working fine for a long time now. I even use it on mobile, which is a lifesaver.
