Reasonably ok, small problem Rated 4 out of 5 stars
Does not block the Large White Area above the Yahoo email page at: mg.mail.yahoo.com .. sometimes it does, sometimes not. And just to clarify, this is a very large Banner Ad from "TurboTax" .. they did this last year around this time and it is back again this year. Sometimes, clearing all the Cookies will get rid of it. Sometimes not. And all my filters for AdBlock Plus are up to date. Firefox 47.0.2 .. Thank youThis user has a previous review of this add-on.
