Q: Safari web content not responding in youtube. How i can fix it?

It could be a flash plugin issue. Try restarting your web browser. If that does not work, make sure you have the latest version of adobe flash installed. Some youtube videos require flash to play properly.

I got same problem.

I checked Adobe Flash on my macbook it is last version (15.0.0.223).

And, I tried to restart but the problem still.

How I can fix it with another solution?

Thanks

This just began today with my unit also (MacBook Pro 2010/ Mavericks). I've update both Flash & Java in the last hour with no success on youtube. It appears to be a Safari issue only since Foxfire seems to run youtube fine. I also deleted DefaultBrowser.plug-in just to see. No luck.
