I need your help.

Before I say anything, this is not an edit just to prank you. Trust me.

OK, so this white bar keeps appearing at the top of the screen on Google Chrome, and I can't get rid of it. Here's a screenshot below.



Oh. That's not it. Here's the real one.



OH FOR GOODNESS SAKES!



OK, you see what white bar (not the address bar)? That needs to be gone. Help!!!
