Works flawlessly and even has a lot of bonus features of what to do with popups if you don't want to just block them. You can put the pages they would open in the background, redirect your current tab to the link, and more. It is very helpful and far exceeds the core feature of blocking annoying popups.

I hadn't had a pop up problem until I installed this add-on

I've been using this for a couple of weeks and can confirm it works well.

Does a great job for it's size, it's very customizable, notification settings are excellent, it's easily understandable and I would recommend it to everyone (implying the user has basic knowledge to control a popup blocker). Thank you!

This is the best pop-up blocker on the add-on store. It's super light weight and blocks all pop-ups.

It is not working

It does not block Mastercard site on Crypto.

And for me, since my text size is a little larger than normal I could not see any method for removing the popup, which prevented me to using the web site. The two buttons for dealing with the popup, provided within the popup by Mastercard, were not seen by me and so I was not able to use the web site until I guessed that there might be some hidden buttons; which I then revealed by scaling down my font size. Such is the stupid life of Windoze users. I was using Firefox on Windows 10. When I browsed to the same web site using Firefox on the Mac, my system effectively blocked the popup without me even knowing it had.

this plugin is working i like it , good job bro :)

Isn't working to stop video pop ups.

Hey, thanks for your extension! It stopped working under current Firefox, until you use the "pin to toolbar" option as per .... support.mozilla.org/en-US/kb/extensions-button#w_manage-pinned-extensions

It used to work out of the box, but I still liked having the button added by "customize toolbar" but that option was completely replaced by this right-click option. Please check this, as I think you're not aware of it. BTW I use current ultramarine Linux with ff v133.0.3 .. I think without the icon, the extension can't notify and so decides not to block at all ... :(

Amazing i love this and free to use
