How do I remove a website from Ubuntu’s web applications?
I accidentally installed the youtube unity web app, and now a "youtube" icon appears in my dash. When I click on the icon, a firefox window opens to "http://www.http.com//www.youtube.com", which appears to be a generic domain squatter landing site. I've uninstalled the "unity-webapps-youtube" package, but the icon is still there.
