To whitelist YouTube channels in uBlock Origin

Install the user script.
Add the following bookmarklet to your toolbar: it will create a whitelist directive for you to add to uBlock Origin for the channel owner of the current Youtube page:
uBO: YT channel whitelist directive (change as you wish)Bookmarklet URL/location:
javascript:(function() {"use strict";var e = document.querySelector('[id^="watch"][id$="-container"] [itemprop="channelId"][content]');if (null !== e) {var t = e.getAttribute("content") || "";if ('' !== t) return void prompt("uBO whitelist directive for this channel:","youtube.com/*user=" + encodeURIComponent(t) + "*")}alert("No Youtube user name found on this page.")})();
Once you click this bookmarklet while on a Youtube page, it will extract the channel owner's name and create a valid directive to be pasted in the Whitelist pane of uBlock Origin if you want to whitelist the Youtube channel.
