Browser has an image superimposed
I have a piece of QR code stuck in the upper left hand corner of the browser. I'm guessing that it's a QR code is irrelevant, rather that it's part of a graphic image. How can I get rid of it?

Start Firefox in Troubleshoot Mode to check if one of the extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) or if hardware acceleration or if userChrome.css/userContent.css is causing the problem.
- switch to the Default System theme: "3-bar" menu button or Tools -> Add-ons -> Themes
- do NOT click the "Refresh Firefox" button on the Troubleshoot Mode start window
