Worked great for awhile and then I YT homepage would redirect to a channels page. After a lot of trying to figure out what was going on I read a page here https://support.mozilla.org/en-US/questions/1246592 that mentioned others having the same issue that all had this add-on. So I uninstalled it and that fixed it. So not sure whats going on but if your YT home page keeps redirecting to a different page this add-on might be the culprit.
