I think this is a recent regression, possibly caused by bug 935640. Steps to reproduce: - Install Shane's demo provider at http://mixedpuppy.github.io/socialapi-demo/ - Do something that causes the "share location" prompt to appear. I'm not sure what the easiest thing to do to trigger it is, but it happens whenever I restart the browser. Expected result: Notification attached somewhere that makes it obvious it's related to the sidebar. Maybe to the icon in the header of the sidebar? Actual result: Notification attached to the location bar. See attached screenshot.
