Thanks for the feedback. The chrome/firefox pages have user reviews but there aren't many of them. I was sensitive to performance when I wrote it - in most cases detection rules are single selectors. It won't run anything on sites not in the db. No library dependencies. There's a phantomjs test suite that flags false positives and negatives. Of course, I can't personally compile a list of every site with sponsored content, so if it's not on the list the addon won't display anything. If you're interested, the code is open source at http://github.com/typpo/ad-detector http://github.com/typpo/ad-detector. Hard for me to say whether it can spot ads that you can't. Many people think they aren't susceptible to ads like these, and I'm one of them, but I built this for peace of mind. Sponsored content can be easy to miss. My favorite examples are this Yahoo news article on climate change (written by an oil company), and a Newsweek article on personal injury lawyers: [1] https://finance.yahoo.com/news/global-cooling-real-inconvenient-truth-140500879.html https://finance.yahoo.com/news/global-cooling-real-inconveni...
