works fine! Don't forget to allow the extension to work in private modus

Good

quit useful,

This really blocks nearly everything (only two or three things on webbrowsertools popup-test site were not blocked when I tried it).

This is the perfect complement to the built in protection in Firefox. The Popup blocker in Firefox does not stop full page popups or redirects, this lightweight extension does.

A must have along with uBlock Origin, a lot of popups still slip through Firefox's popup blocker, with this extension you won't have to worry about any popups.

AWESOME SET AND FORGET
SET AUTO ANSWER TO NO NEVER NEED TO WORRY
BLOCK JAVASCRIPT POPUP AS WELL

Stop to work... after last firefox update i have popups all time.

What does clicking the icon do? Either it's grayed out or it's blue, but it still blocks popups? I don't get it.

Works perfectly and exactly as I hoped! The numbered explanations are very, very helpful! Now it's just a matter of time to add all of the pop-up sites in the lists. :D

muy bueno
