It's very good

Add-on is very useful for blocking pop-ups and works extremely well at catching them, however I have an issue where when I receive a request and allow it, Firefox itself notices a pop-up and blocks it so I end up closing the notif for that a lot, if I set Firefox to allow pop-ups then when I allow the add-ons request I get a duplicate tab for the pop-up, I modified my Firefox browser a lot like the config and I have a lot of other add-ons so I assume I might have changed something that made this happen so take this with a grain of salt.

works very well

worked for me. thank you!

Muy buen complemento. Me bloquea hasta las ventanas de algunas páginas que, con frecuencia, se saltan los bloqueos de popups del navegador. Y hasta eso, da opciones para abrir o denegar la apertura de la ventana. Muy bueno.
