I have a gray background at top of page behind navigation toolbar and other toolbars. It's not part of the theme. How can I change it?
After installing version 4, all web pages have a gray background, with blurry diagonal stripes, at the top, behind all the toolbars. It is not part of the theme and is unaffected by changing themes. It does not extend down to the rest of the page. I don't like the way it looks and would like to change it. I'm not sure if this is a default, or something that I inadvertently did myself. It has been there since I first installed. Any ideas?

You may have installed a persona.
You can uninstall your current Persona and revert to the Default theme (Tools > Add-ons > Themes).
