My approach was to start by combining SomeoneWhoCares' and MVPS' hosts files with `uniq`, which rendered such browser addons largely, though not entirely, unnecessary. The down side is you can only do that on machines where you have root access.
Hosts files only work for redirecting known bad actors down the memory hole. A noscript style blocker is needed to catch malicious js from new sources not tracked in a hosts database.
