One of my must haves... yet flawed Rated 4 out of 5 stars
Great addon, but with 1 flaw. I wish you could set it up to block bad sites without having to deal with a popup window for EVERY single site you visit... even though you have popups disabled.
Also, the page takes the liberty of loading in the background as you get the popup asking whether to allow or leave the site anyway. That shouldn't be the case. It should be blocked until you make your decision one way or the other. It's a good thing I have NoScript and ABP in place too.
Fix these things and it gets 5 Stars.
