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

Best

Needs an option to "do not block" as default, instead of having to whitelist websites one by one. So it would *only* block the websites in a blacklist, instead of only *not* blocking whitelisted ones.
Other than that, I really like that it's easy to disable, requires few permissions and works well.

Edit: Fair answer. Upped my rating to 4. Honestly, my real issue is that it keeps blocking important popups like "Login with Facebook" buttons, and I have to keep setting up those sites one by one. Not sure what'd be the best solution for that.

great

It works!

Flawless extension. Thoroughly satisfying. Strongly recommended.

Great, fast and useful

I installed this addon because I was annoyed by a popup and Firefox on Android is not able to block pop-ups. This addon works and disables the popup.
There is no convenient way to manage settings for sites, so if you (accidentally) allow or block pop-ups permanently you have to clear all site settings in Firefox in order to revert the setting.

Edit in response to dev:
Thank you for the fast reply even if the reviews is not the right place. Clearing site data did help me. I updated my review.
(And please be a little less insulting on people who don't give 5 stars, have 4 for a really good addon, 5 if you improve the settings)

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

I created a Firefox account just to review the app.
4 stars totally earned! I would like to have it also for Safari...and then will be 5 stars :)

To the developer: Thank you a lot! I was looking for something like this for a very long time!!!!

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
