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

Thanks

A real web-life saver! :)

Helpful Popup Blocker for me

Dear developer I don't know how I can thank you.
I am using it on mobile device and it works seamlessly thanks for the extension.

It is a life saving extension.
My only qualm is that everywhere I click, I get notified that facebook pop-up was disabled.
That's awesome, but I swear it's happening too often.
I would love to be able to mute some notifications, while keeping all the blocking features intact.

Clear instructions in FAQ, met all of my needs. Someone who is that thorough in creating a user guide/FAQ has all my respect.

Works great, and unlike other similar addons its source code can be reviewed at github.
