Super useful for those who are willing to put up with the extra effort. As with everything that improves your security/privacy, there is a time cost.

One star for version 0.4.2 that started to report all popups and new tabs to Web of Trust (WOT) by default, a company that sells user identifiable data to third parties. The usefulness of this feature is dubious, the countdown is poor usability, WOT is not a good measure of a popup being wanted and the privacy leakage is too great.

kinda help

Seems good so far

Cumple lo que promete.

This is a very good add on, it works great. The only flaw I have noticed is some sites seem to be able to load before I can click "block". If there was a way to stop the site loading until I choose to click "load or block", it would be better. Other then that, its a great add on! Keep up the good work.

Version 47 ????

Works like a champ

Indispensável

Loved the idea and cleanliness, but then it pushed all 8 cores of an i7 7700K to 100% just to block a single pop up site. It seems to be a problem with FF Quantum itself, though. Try it on TPB, click on the search bar of that site as if you were to input some text and check for yourself!.

After trying different ones came back to this one!. Thanks to the developer.

I use this for Opera, FF, and Edge. For some reason, this extension causes RAM chewing issue only with FF. This is an only extension I use for all browsers I have and FF begins to chew RAM up to 1GB/hr or 2GB/3hrs in idle. The problem does not occur with Edge and Opera (or any other Chromium based browsers). I am not sure if it's caused by codes of FF or of this extension but the problem exists with all of FF, FF Dev, and FF Quantum. Besides that, this is "the solution" I found for blocking popups.

Does an alright job of blocking popups. But this app alone keeps popping up a window about the app, donations and it's website. Seriously frustrating.

Doesn't seem to be blocking anything even after tinkering with the options. Well done Mozilla for forcing an update on us that doesn't appear to let any popup blockers work... I'll have fun avoiding all the malware these things are trying to force on me.
