I was testing it, and yep, it works, and really love it! Thanks for creating such a good Firefox add-on. I shared it to my friend, he also hates popups

idealne uzupełnienie dla adblocka <3

It works!

Flawless extension. Thoroughly satisfying. Strongly recommended.

Great, fast and useful

NICE WORK...HAPPY USER !!!!

I was using a very popular competitor popup blocker and began having problems with it blocking form elements as well as privacy concerns. I tried Popup Blocker Ultimate and am very pleased with its performance.

It is very easy to whitelist sites that you want to enable popups. Very Effective lightweight popup blocker. Highly Reccomended

Does what it says.

does what it says it does perfectly, as long as the website your watching/browsing on allows it

Really does work

keeps annoying pop ups away allowing u to visit even the most annoying websites by blocking them

Works great no popups at all unless user chooses to whitelist

excellent popup blocker for firefox <3

works as advertised

Sehr effektiv für jegliche ungewünschte Einblendung. Bester Blocker, den ich jemals hatte.

Works perfectly but Zemana antilogger find this in the extensions folder of my profile

extensions\{60b7679c-bed9-11e5-998d-8526bb8e7f8b}.xpi

Is that normal? All the other extensions i use have no problem or strange things which zemana finds

Great
