uMatrix or uBlock (in advanced mode) can largely accomplish the same in a simpler way. However, in my experience, if you go the 'default deny' route against scripts, the spread is about 33/33/33, with 33% of the pages working perfectly, 33% breaking in small ways, and 33% completely borking up. Yes, you can then add the necessary scripts to a whitelist, but it gets tiresome to constantly have to 'fix' sites.
Whitelisting is indeed troublesome, especially in the age of CDNs, and not really worth it for sites visited only once. I discovered that some instances of breakage can be fixed by enabling Firefox "reader view", for others I just start
chromium --incognito
Nice

NoScript rocks!!!
In my opinion, JavaScript should be disabled by default and only enabled for specific tasks or websites. Not finding exactly what I was looking for in any other browser, I eventually created Privacy Browser on Android. https://www.stoutner.com/privacy-browser/
There are extensions like No Script that can give similar results for other browsers. https://noscript.net/
