### :small_orange_diamond: Clear window.opener
👼 Don't use this. Instead use earthlng 's strict [windows.opener be gone](https://github.com/earthlng/testpages/) or [CanvasBlocker](https://addons.mozilla.org/firefox/addon/canvasblocker/), which supports `window.opener` protection with whitelisting (see CB's "Window API")
