Is AdSkipper – Skip Ads Fast safe?

High risk

AdSkipper receives remote configuration from extsoft.info that can inject scripts into visited HTTP and HTTPS pages.

The extension opens extsoft.info during installation and stores configuration from that page for later use. That configuration is later fetched and can add remote-controlled elements, including scripts, to every completed top-frame HTTP or HTTPS page visit, and it can redirect matching navigations while appending the original URL in base64.
