after the update works incorrectly
shows an incomprehensible page on the livejourmal.com

impossible to show this page.

Poorly documented. Loaded with techy jargon. Few to no examples given of what is considered a "popup" - no graphic representations. I am still bombarded with pop up boxes and dialog windows and request to spam with notifications despite "strict" labeling.

HORRIBLE HORRIBLE HORRIBLE. I installed this to block pop-ups and instead "MY quick converter" has taken over my computer! Now I have to figure out how to uninstall all this crap. I thought this would be a trustworthy Firefox add-on. It is NOT!

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.

Version 47 ????

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.

Not sure the dev knows what a pop-up is... this things blocks nothing

DOES NOT block the nastier popup windows, the whole reason you have a popup blocker...doh
Certainly NOT (Strict)

not working in any way i can see. (cant tell if its on or off.)

Doesn't work.

Doesn't work. I installed it, restarted Firefox, opened a web-page only to immediately get a pop-up ad.

As others have said, it doesn't work. Pretty poor for a Featured Extension.

does not work. has many problems

not working well with containers (often opens in non container tab, sometimes get option to open in specific container); unable to trust and open in background;

After installing weblinks didn't work on major websites like CNN and ESPN.

Youtube won't work with this addon. For so all, I tried to find what was wrong with youtube not loading, it's this addon!. Uninstall and you're good to go.

Removed add-on as unable to access YouTube(white blank page)even when disabled on browser!

its useless with openload videos nothing can beat its every-click-popups that means the technique that openload use it could any site use it as well so fix it quickly or you will get a ton of -1 rate!!

certainly can not block popups of openload.co

It doesn't appear anywhere in the UI.

doesn't block all popups, https://addons.mozilla.org/en-US/firefox/addon/simple-popup-blocker/?src=api is better

popups were blocked from the get-go for even links (javascript links that opens windows) i did not need blocked. I uninstalled the addon but the links are still not opening the popup window. Reinstalled my browser but lots of java links on different sites are not working anymore. Need to revert my browser back to before your addon. Im not really asking for help, Im sure i'll figure it out, I just hope this review helps to improve your product
