My script is not to remove the popup warning you shown, it just bypasses Ads. So, please try disable any ad block extension, clear cache, and restart your browser. Make sure NO other Ad blocker extension is enabled when you visit youtube.com.
well, now I can confirm it won't work, already add youtube.com to the whitelist, left only this script, but still got the pop-up warning.
