Nice add-on for Mozilla.

AdBlocker Ultimate has been used in our household for a long time. We also have used it's cousin, ABP. Anyway, as a cybersecurity professional, I hate annoying and intrusive ads. I want to load the site, do what I came for and leave. There is a time and place for ads so the feature to allow them on certain sites is welcome and appreciated. This has a 12 out of 10 rating. Meaning you need this extension and should support it once in a while with a little cash injection. Show the developers some love!

Claims to help you "focus your attention on the content you want" and that it block "Overlay ads," then it shows an overlay ad asking me if I enjoy it. No, I do not enjoy popups and overlay ads, so time to remove this extension.

All are ok!
