AdBlock Plus is a great extension; it does what it says it will, generally. One issue I'm finding, though, is that there are one or two very intrusive pages/companies that AdBlock Plus is not stopping the pop-ups from (e.g. EToro.com). I wish AdBlock Plus would provide a "Blacklist" page, as well as their "Whitelist" page because I want AdBlock Plus to make an effort to stop these pop-ups.
