Kill certain functions often used for popups and spam.
Unlikely to be of any use to you unless you want to click a bunch of confirmations to allow legitimate websites to function. It does effectively block a lot of popups and other junk, but at the cost of also killing a lot of legitimate site functionality. Simply overrides window.atob, window.eval and window.open functions, preventing them from doing what they're supposed to. Primarily published in the chrome shop to avoid chrome nagging me to disable "unsafe" extension on my own devices.
