Embedded videos not loading. Please Help!

When I go to several blog sites, I notice that videos (normally from Youtube) that are embedded within the page are unable to be seen at all. I instead get a big white box. HOWEVER, if I were to "OPEN A NEW TAB" from a link with a video, the new page with the video shows up as long as I don't view the new page until it finishes loading. (If I opened the new page in a new tab and then viewed that new page before it fully loads, the white box would appear.

This is peculiar because on my other Macbook Air (same model and OS, just different specs), never had this problem; the videos that are embedded can be seen; the user just needs to click on the player for it to start playing, and I could do this whenever I wanted to.

This is extremely frustrating considering the fact that I need to fully wait for a new page to load before even opening the tab.

no one? I reinstalled flash, but same problem...

 

That's odd. Safari seems to be showing the videos just fine... I refuse to go back to Safari though. Diagnosis?
