It works Rated 3 out of 5 stars
To be honest, I cant see to what extent this add-on works since I'm using other measures to avoid/block ads, although it worked with a hard to block ad that was bothering me every time I visited a site and no other add-on/cookie blocker could get rid of, so thumbs up.
I don't agree with the developer regarding whitelists though. Also, this add-on is 100% non-intrusive and invisible, which is both good and bad. I appreciate not having to mess with settings, etc., although a bit of personalisation or a list of filters for people with none or little knowledge of programming would be appreciated.
