How do I get rid of these new ads on Facebook?

[Christa]

Yes, I know there have always been ads on Facebook, but they're on the side where I don't pay any attention to them. However the past week my Facebook has been putting an ad in the top right corner and then after every two stories on my news feed there's another ad. And when I view pictures and click to the side to go to where I was originally Google Chrome takes me back to the last site I was on, i.e. if I was on Yahoo before Facebook I'd be brought back to Yahoo. It's getting annoying and I've tried uninstalling Google Chrome but it still does the same on Internet Explorer and I changed my password on Facebook.
