YouTube Ad Skipper is an extension that auto skips ads after YouTube provides a skip ad button. It does not block an ad.
A browser extension that automates skipping ad on Youtube. This is not an ad blocker, it just automates the process of clicking on the "Skip Ad" button on Youtube.
This is basically useful when you are watching a youtube video (or a playlist), and an ad starts playing. Youtube allows you to skip the ad after 5 seconds, but if you can't be bothered to click it yourself (or you are AFK), this extension clicks that button for you.
