I tried manually disabling all of my Chrome extensions and clearing my cache but none of that helped. Just today (8/20/2013) I see that there is a new Chrome update available. One of the features is a new "Reset browser settings" button. It resets everything back to the default settings but keeps basic customization like bookmarks, themes, etc. I thought it would remove all of my extensions but in fact it simply disabled them.
I'm glad to report that this DID fix my issue with embedded videos! I then went back in and enabled all of my extensions again and the embedded videos are still working! Woo-hoo! So whatever this reset did, it took care of my problem.
Here's how you do it:
- In your Chrome menu, hit the icon with the 3 horizontal bars (called "Customize and control Google Chrome")
- Select "Settings"
- Scroll to the bottom and hit "Show Advanced Settings"
- Scroll to the bottom again and hit the button labeled "Reset browser settings" as seen here...
