1. Describe the problem you are having posting a youtube link.
  2. Ad-Blocker was removed from version 9. The reason is unknown to anyone I’ve asked. However, if you still want, which I did which is why I still have it installed… add it from version 8.0.1497. When you upgrade to 9, the adblocker is seperate so it will not be uninstalled and you will still have it.
