The Best
one of the reasons why I am using FireFox

Perfect add-on! But I agree with @bridgerman - a simple White List function would be useful.

This add-on is extremely useful 100% effective and easy to toggle

Works perfectly, exactly as sescribed. Thank you.

I think Mozilla should allow developers to receive voluntary donations limited in value to reduce accidental overpayments what would make the system safer and more trustworthy for a long-term future.

nice

best pop up blocker in any platforme theres no need for a whitelist since you can do it just from permissions at the top left corner of the url and allow the open pop-up windows

Good

This extension literally blocks ALL the popups i don't need, even some that i need but i don't mind!

It never fails. A must for secure browsing!
