I was discouraged somewhat before using this addon... it is utter genius! Really the very best imo. It does what the others can't seem to do. It has helped make the internet a joy to surf again. 100% must have. (Occasionally, you might click on a page link and nothing happens... well just hit the icon and either untick briefly or add the domain to its whitelist... easy.) Thanks, many regards Mojtaba.
This add-on has become a must have for me thanks to the transparency of its privacy policies, and the effectiveness of the Pop-up blocking of course. I recommend this add-on to everyone that wants to experience a smooth web surfing without sounds in the background from hidden browser windows, ads or ultra fast redirects that often get out of your control. I'm giving five starts because six is not possible :)
It's the best option right now. The extension it's greatly integrated with the browser, it doesn't collect any website's data, so it cares about privacy as well, and the user experience and UI is straight forward, everyone can use it without any problem.
