Have you turned on the setting that allows AdBlock to whitelist individual YouTube channels and restarted your browser? If you have and you still aren't able to whitelist a YouTube channel, please try these troubleshooting tips.
"Allow whitelisting of specific YouTube channels" doesn't appear in AdBlock's options
YouTube channel whitelisting doesn't work with Safari Content Blocking. That means that if you use our Safari extension or the AdBlock for Safari app, you can't whitelist YouTube channels.
Make sure that you're using AdBlock and not Adblock Plus (ABP) or some other ad blocker. Only AdBlock features YouTube channel whitelisting.
Try clearing your browser cache and restarting your browser.
If you still don't see the option to whitelist specific YouTube channels, you may be using an older version of AdBlock. AdBlock should update automatically, but if you have extension auto-update turned off, it might not. Manually update AdBlock.
We know of an extension called YouTube Magic Actions that breaks YouTube channel whitelisting. This has been reported to the extension's developer.
If you don't have YouTube Magic Actions, check your extensions for other possible incompatibilities. Disable all of them (except for AdBlock). Allow whitelisting of specific YouTube channels should appear in AdBlock's options on the GENERAL tab. Re-enable each extension one by one until the option disappears again. The last extension you re-enabled is the culprit. Disable it for now, and be a good citizen by reporting the issue to the extension's developer. :)
"Whitelist (name) channel" doesn't appear in the AdBlock menu
If you're using Safari, make sure that Safari Content Blocking is disabled in AdBlock's options. This feature prevents AdBlock from whitelisting individual YouTube channels.
In any browser, try clearing your browser cache and restarting the browser.
Those suggestions didn't help. Now what?
Have you gone through the steps above and the YouTube channel whitelisting option still doesn't appear, especially in Chrome and Firefox? You have probably encountered an issue first reported by our Chrome and Firefox users in the spring of 2019.
What's causing it is a simple timing issue. Our YouTube channel whitelisting feature relies on a particular YouTube API. (An API is basically a way for two unrelated software applications to "talk" to each other.) This particular API has an upper limit on the number of "conversations" AdBlock can have with YouTube each day. It's reset at midnight UTC (Greenwich Time) every day. Basically, we've started running into that limit. Folks who have whitelisted YouTube channels find everything's working fine in the morning, but by evening AdBlock has hit that wall and further YouTube channel whitelisting requests are "turned away."
We released an update in late spring 2019 that addresses the issue. As more and more folks get the update, this should become less and less of a problem.
In the meantime, if you're viewing videos in the evening and no ads are appearing on a whitelisted channel, or if the whitelist option doesn't appear on the AdBlock menu, just pause AdBlock, then reload the video to get the ads to appear. :)
