I have tried several blockers but this actually stops the pop up before it happens.

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.

Thanks

A real web-life saver! :)

Helpful Popup Blocker for me
