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

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.

Whitelisting doesn't seem to work for onedrive and office online

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.

Props to being the ONLY popup blocker I could find that doesn't have its own popups, doesn't ask for money in their own popups, doesn't transmit and collect your browsing data (yet no privacy policy posted that I can find), and has the extension up on github.

Its work Fine but not 100% perfect and i like to use, sometime when i open more than 10 page this extension is not working right.

This is great one but I have one complain !

Default action when a popup action requested ........................
The previous control option doesn't work. only "Do nothing" option is working and the others not.

Note: I am using firefox

Loved the idea and cleanliness, but then it pushed all 8 cores of an i7 7700K to 100% just to block a single pop up site. It seems to be a problem with FF Quantum itself, though. Try it on TPB, click on the search bar of that site as if you were to input some text and check for yourself!.

After trying different ones came back to this one!. Thanks to the developer.
