In Chrome, you can in fact white-list certain websites. It's actually quite nice. In Chrome, the advanced settings has an exceptions button that allows you to include websites that can bypass the rule.
How does that work for a site that imports JS from multiple domains, as is usual? Does adding the top domain mean that it can load JS from everywhere, or do you have to manually find out which domains it needs whitelisted to work? Neither solutions seem particularly attractive; NoScript allows you to enable JS for that domain and stuff like CDNs without having to allow other sutff.
