For Firefox, the real comparisons are Request Policy and ublock (origin) in advanced mode (for chrome, umatrix). These do full third-party host whitelisting per domain. So every time you visit a website on a new domain, by default all requests to third parties are blocked. Then you spend a few minutes working out which ones are required.<p>By comparison, noscript simply blocks javascript from third parties. It does include a number of anti-xss heuristics though.
