961784 - Various event listeners from shell.html don't work when loading it in a firefox tab

Status: RESOLVED FIXED

(Firefox OS Graveyard :: General, defect)

Description

[Alexandre Poirot [:ochameau]]

When running b2g in the mulet (bug 943878), various event listeners fails and are never triggered. Listening on the system app frame for touch events, or listening on shell.html global window for key events aren't working.
For both cases, we have to listen on the chrome event handler, which is the firefox tab <browser> element.

uber-nit: alignment with .QueryInterface(Ci.nsIInterfaceRequestor) :)
