So for the last couple of weeks, Youtube has been wonky for me. When I first pull it up, everything is as it should be. But once I find a video to watch and click to play it, the play screen will jump to the right side of the page instead of staying on the left. When it does this, all of the advertisements and video suggestions end up blocking part of the screen.

I tried the CRTL F5, but it didn't help. Any ideas?
