Whatever safari or chrome or firefox, can't open youtube, but any other websites. I've updated the flash, use shift+restart to perform internal repair operation, check my DNS that all are gray. Still don't help. Any one can help me? Many thanks.
MacBook Air, Mac OS X (10.7.4)
Try a different DNS sever...
Open System Preferences / Preferences then select the Network tab. Click the Advanced tab then click the DNS tab.
Click +
Enter these addresses exactly as you see them here.
208.67.222.222
Click +
208.67.220.220
Then click OK.
if that doesn't help, open System Preferences > Flash Player then select the Storage tab. Click: Delete All
Try uninstalling Flash then reinstall > Troubleshoot Flash Player | Mac OS
Very important to uninstall the currently installed before reinstalling new.
If you have the ClickToFlash extension installed, that can prevent Flash based video from streaming. It can also be installed as a plugin in /Library/Internet-Plug-Ins.
For Safari ... check to see if Safari is running in 32 bit mode. Right or control click the Safari icon in your Applications folder then click Get Info. If the box next to: Open in 32 bit mode is selected, deselect, quit then relaunch Safari.

yes I've add the addresses in DNS and reinstalling flash player following your instruction. But it still doesn't work.
I had the same problem, every website would load just fine except for youtube. When I added those two ip addresses into my dns then it suddenly started working just fine. I have no clue why or how you knew to do that, but thanks a lot.
browses can open all websites except youtube
