I'm surprised NoScript actually contains a whitelist, I didn't expect it to. I personally switched to Policeman (https://addons.mozilla.org/en-US/firefox/addon/policeman/ https://addons.mozilla.org/en-US/firefox/addon/policeman/) a while ago, and there it's pretty clear that you can remove the built-in rule set. I actually like it better than uMatrix: policeman shows you the full url of the blocked resource that you can inspect before allowing, and cross-domain request are very easy to follow. The only thing I wished is per-domain control of most modern browser extensions, like, for example: disable CSS animations everywhere except when I allow it to. Likewise for <audio>, <media>, GL, and whatever useless feature I don't need 99.99% of the time. uMatrix has already per-domain boolean control of "agent spoofing" and related settings, it would be awesome if the above would be included there. NoScript was a bit more forward thinking in that regard: you can disable media/GL globally except for whitelisted sites, but then again without cross-domain control you end-up whitelisting everything.
