I don't personally consider netsurf a good investment against trackers; there are plenty of single pixel trackers that firefox's tracking protection has recently revealed to me, plus there's no option to ask whether to accept every cookie or not - just a blanket accept all/deny all option as I recall, although it's fair to say I've not used it in a while. It still has value on a battery powered device though, not wasting cycles running that javascript engine (they were working on it when I last used it, but I assume it's still optional).
