Veeeery nice. It really blocks instead (like other "popup blockers") closing after they popped up.
No more beeping scam sites when watchin Videos.

Works, Doesn't bother me expect after Firefox updates, which seems infrequent enough. Best popup blocker I've ever used, but I've only ever needed one.

Awesome job Mojtaba!

I like about the addon:
1) it works
2) that the developer doesn´t track personal information.
3) it´s free.
:)

The best add-block plugin I've tried so far, it really blocks them all! A big thank you to the developer, no more fast clicking to close those unwanted pop-ups.

Works very nicely

It's great add on. I suggest it to every one who is care about his privacy.

It works as expected! Very nice, thanks! :)

Superb add-on. Did exactly what I needed with zero fuss. Thank you!

Works fine !

It works like a charm. It does what we want, it's not obstrusive, simple, very useful for me. Good job, thank you

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.

Popup Blocker Ultimate prevents *most* distracting, annoying popups from cluttering my view of the sites I'm visiting. It's a BIG improvement!
Thanks, Mojtaba!

Excellent add on, block any ad pop ups that ad blockers dont can block, recommended 100%

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 :)

Ótima extensão! Instalei faz alguns dias, devido ao bloqueio do Poper Blocker, e não decepcionou!

AWESOME!

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.

Helped seamlessly block popup windows I was getting on several websites. Highly recommend.

Works 100% nothing negative.
