Installed to block one nasty site. It failed. Otherwise was working as expected until I found that it blocked my banking website. Despite whitelisting the domain (citi.com) and everything else I could try, the only recourse was to disable the add-on.

Trying to use Firefox in lieu of Google. I'm an FNG.

Works really well most times, actually, but sometimes, when I really need a pop-up to open (MS Office online, secure payments, etc.) and I turn off the blocker (icon greys out), it still blocks the pop-up. It's really annoying having to go to the plugin manager and disable the blocker, do my thing and then having to enable it again.

A big crap! It is not the most efficient and is extremely boring and dumb. Don't keep your options. The "Popup Blocker Ultimate" is much better.

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.

This is very helpful, and really cleans up my screen. It stops those I have blocked. My main request: when i have blocked one, simply stop repeated attempts by the same popup rather than asking me again and again.

Popup Blocker (strict): Pop-up blocker that actually works. Has nice, neat options in preferences tab.

Funktioniert leider überhaupt nicht.
