Popper Stopper Pro

From the original founder of "Poper Blocker" - New defenses & algorithms that were built from the ground-up. No more undesired windows and tabs!

This extension prevents popups and popunders from appearing, and gives you back the control of your browsing experience.

A notification will be shown when a block occurs so you'll have the opportunity to decide whether to keep blocking the window or to whitelist windows from that site using the “Allow Always” option.

The extension works well with ad-blocking extensions like adblocker and ublocker origin.
