Is RedBlock - Block ads on Youtube™ safe?

Clean risk

RedBlock downloads rule code from redblock.cc and injects generated scripts into YouTube pages.

RedBlock fetches versioned rule JSON from redblock.cc and stores the returned rule slices in the browser. On YouTube pages, its content scripts copy those rules into page storage and inject generated main-world JavaScript that can change page behavior, including fetch or XHR responses, timers, window properties, and matching script or text nodes.
