    Steps to reproduce:
    
    1.  Download Firefox .DMG (English) from Mozilla site to a Mac running OS X 10.9.5.
    https://download.mozilla.org/?product=firefox-32.0.3-SSL&os=osx&lang=en-US
    2.  Double-click .DMG to mount.
    3.  Drag/drop Firefox to /Applications
    4.  Double-click Firefox
    
    Actual results:
    
    OS indicated following dialog:  "Firefox.app" can't be opened because the identity of the developer cannot be confirmed.
    
    See attached file.  This has occurred with at least the last two security releases of Firefox (32.0.2 and 32.0.3).
    
    Expected results:
    
    Should have been prompted that I'd downloaded a file from the Internet and did I want to continue.  Instead, I had to go into System Preferences | Security & Privacy, and override the fact that Firefox was not properly signed by clicking on an [Open Anyway] button.
