Doesn't seem to be blocking anything even after tinkering with the options. Well done Mozilla for forcing an update on us that doesn't appear to let any popup blockers work... I'll have fun avoiding all the malware these things are trying to force on me.

Excellent popup blocks. Very strict in nature.

No esta en español y un poco confuso sobre la eleccion

Nice

Hi,

ff44 allows me to use all addons without severe compatibility issues, that's hwy i'll never update
to the latest ff to break 10 or more addons functionalities.

It would be nice to send me an up to date version that allows me to have the functional icon
on firefox toolbar, using v44.

Not sure the dev knows what a pop-up is... this things blocks nothing

Too strict most of the time. Blacklist mode sometimes doesn't work.

Better to add a shortcut to add a domain to blacklist. Or at least add a link to open the options. Otherwise it's really wearisome to add blacklist item.

Disabled the add on most of the time. What a shame.

Sembra proprio fare il suo dovere,grazie tante

DOES NOT block the nastier popup windows, the whole reason you have a popup blocker...doh
Certainly NOT (Strict)

nice blocks all the stupid adds

not working in any way i can see. (cant tell if its on or off.)

Doesn't work.

Danke

Doesn't work. I installed it, restarted Firefox, opened a web-page only to immediately get a pop-up ad.

As others have said, it doesn't work. Pretty poor for a Featured Extension.

does not work. has many problems

not working well with containers (often opens in non container tab, sometimes get option to open in specific container); unable to trust and open in background;
