One of the reasons for a 4 star rating on most all the ad blockers and popup blockers I give is because a number of popups might be presented as blocked but there's no information on what popups are blocked: i.e. the url of the blocked popup. Ad-Block and many others simply do not provide the offending url. I understand there is a great deal of overhead with keeping a log of what was blocked. A simple way of turning on and off the logging process could be added to make the experience better. A feature in the advanced options to make the class active and an extra button on the pull down window to start and stop the log would get 5 stars from me. You'd have something no one else offers.

its good.not great but good.Blocks 99% of ads.i wish it has an pop up blocker in it.then it would be great

I enjoyed this add-on because since I'm using this, I'm no longer get constant pop-ups whenever I'm on some sites.

An amazing add-on that i use on every browser. Works flawlessly.

Very good.

This addon is great. Blocks all popups and it allows you to whitelist. I got it specifically to block the popups that just won't stop on certain shady websites that allow you to view movies or shows etc and it works perfectly.

Really works great! I usually get annoying pop ups from streaming site but haven't got any since downloading.
THANK YOU :)

Popup Blocker Ultimate blocks almost all popups that other pop up blockers fail to stop. And the dev is honest and does not sell our usage data or other dubious practices. I seriously recommend to support this guy with a donation, honest behavior and good quality should be rewarded!

And for the love of god, those of you that whine about the page that asks for a donation: that page should not show more than once when you install and once when you uninstall. However I have noticed that it may also appear after updating Firefox. But in any case ffs, stop whining! This pop up blocker is super awesome, it works really well, it's FREE, and the devs does not sell our browsing habits or usage data or other such nonsense.

Great addon

works how it says and is very user friendly

Have nice

it was fine before ,now not working on some website which i use the most having so many pop up windows opening yet, previous version was more effective

works great

I've tried differents pop up blockers before installing this one. This one is by far the most efficient. (05/2018)

Blocks annoying popups where other popular extensions have failed. For example the notorious torrent site RARBG no longer open popups/links.
