Occasionally, you
might come across a video on YouTube that warns you that the content may be
inappropriate for younger users. To view it, you’ll need to sign into the site
and confirm your age. That’s no big deal, but if you’d prefer not to waste time
doing that (or would rather not have the video stored in your account
history).
You can bypass the
youtube age restriction. Remove the ‘watch?’ part in the URL and replace the
'=' with a ‘/’ so that www.youtube.com/watch?v=xXUjpHHfTLY becomes
www.youtube.com/v/xXUjpHHITLY.
The video will open full screen, without showing the rest of YouTube and you
can now watch it without signing in.
