The problem may be caused by a bug in OS X, triggered by "Flash Player."

If Flash is installed and you haven't already done so, please update to the latest version by opening the Flash Player pane in System Preferences and selecting the Updates tab.

If Flash is already up to date, or if the update doesn't solve the problem, open the Safari preferences window and select the Security tab. Uncheck the box marked

Allow Plug-ins

See whether there's an improvement.

You can watch videos on YouTube and some other sites without using Flash by installing the "ClickToFlash" or "ClickToPlugin" Safari extension. That's not an endorsement. You must always do your own research to determine the safety and effectiveness of any third-party software before using it.
