An annoying grey box with the text "100%" is displaying on all of my Firefox screens. I do not know what this is or how to remove. Any ideas? thank you.

Do you have that problem when running in the Firefox SafeMode? <br /> [http://support.mozilla.com/en-US/kb/Safe+Mode] <br /> ''Don't select anything right now, just use "Continue in SafeMode."'' If not, see this: <br /> [http://support.mozilla.com/en-US/kb/troubleshooting+extensions+and+themes]
