I'm looking for a website that can detect what web features your browser supports, e.g. CSS3 properties, HTML5 localStorage and other Javascript features.

Main reason I ask is because I'm trying to find out exactly what the NetFront browser inside the Nintendo 3DS supports, but can't find any solid documentation online.

Personally I like this one and how it groups functions and calculates a score.

If you want to compare across browsers without having to test each, quirksmode is quite good.

As far as your specific browser, this page is interesting, listing that NetFront Browser NX v2.0 supports Audio/Video tag, Canvas 2D, Web Workers, Web Storage, WebSocket* (new) and WebGL* (new)
