Sometimes I run in to video.link stuff, formerly known as safeyoutube.net. It's annoying, though, cause it's nowhere as good as regular YouTube.
So here's my kindness: A little bookmarklet to handle it for you. It's nowhere near the best bookmarklet ever, but just drag it to your bookmarks bar. video.link fixer
Please don't use it without permission. There's bad stuff on YouTube, so be safe using it.
