The actual warning comes from nsChromeProtocolHandler::NewChannel2 , presumably caused by trying to load a file that is not registered. I suppose this could be a race, a packaging issue, or a straight up non-existent file. It seems to be referenced in various add-on and extension tests .  http://searchfox.org/mozilla-central/rev/30fcf167af036aeddf322de44a2fadd370acfd2f/chrome/nsChromeProtocolHandler.cpp#138-146  http://searchfox.org/mozilla-central/search?q=chrome%3A%2F%2Ffoo%2Fskin%2Ficon.png&path=
