Q: Youtube videos do not play in Safari
When trying to watch a Youtube video in Safari 10.0, I receive an error message that reads: "Your browser does not currently recognize any of the video formats available." Below that it displays: "Click here to visit our frequently asked questions about HTML5 video." When I click the FAQ page, it shows Safari as one of the supported browsers. The same video will play in Google Chrome. I tried emptying the Safari cache and rebooting the computer, but to not avail.
iMac, macOS Sierra (10.12)

I also had this issue when I upgraded to Safari 10.0 and was able to resolve it easily by turning off my Extensions (under Safari preferences / Extensions tab). By toggling the Extensions one-by-one, I was able to troubleshoot the problem. For me it was "Click to Flash" that prevented HTML5 video from playing. I didn't need to close and restart Safari--turning off the Extensions immediately resolved the issue.
