Hey @ryancramerdesign! I know this is an old request, but it would be awesome if you could consider adding this feature. It should be a relatively small addition, and it would be tremendously useful for some users :)

Using youtube-nocookie.com would be great for privacy, and also for those sites trying to follow regulations (in many cases the cookies YouTube sets are the only non-necessary cookies we have, so ...)
