You can now watch
Youtube videos without any ads! Honestly, we miss the time when we could just
browse through the site without a new ad interrupting our stream every five
minutes. However, a user on Reddit has come to our rescue. If you type an extra
period after the dot com in the Youtube link in the URL, you will be able to
watch any video without a single ad disturbing you.

It does not just remove
ads from the beginning of the video but also all the interruptions that arrive
midway to pause out streaming.

Here’s what Redditor
unicorn4sale has to say about the trick:

“It’s a commonly
forgotten edge case, websites forget to normalize the hostname, the content is
still served, but there’s no hostname match on the browser so no cookies and
broken CORS – and lots of bigger sites use a different domain to serve
ads/media with a whitelist that doesn’t contain the extra dot.”

It received over 4000
upvotes so Youtube might be aware of this loophole. Let’s see when do they find
the time to correct it because until then, you can just put a period in the URL
when copying a link and enjoy ad-less videos. If the trick is not working for
you, then you can always subscribe to Youtube’s premium package.
