    I see nothing like this on any copy or version of Firefox that I've used on
    any of several PCs. As has been suggested, ask on a Mozilla forum.

    I'd be more inclined to remove all traces of the curent version of Firefox,
    perhaps using Revo Uninstaller to get rid of everything, and then staring
    with a fresh installation using a known clean installer from Mozilla. A
    bloody nuisance as you'll lose everything, but if you're that unhappy with
    the situation....

    Cheers,

    Roy

    Granted that I don't know much about all this, but isn't it possible FF
    needs a couple of open ports for information about updates to
    extensions, browser, etc? Just a thought...

    It is pretty normal behavior for Firefox,
    same as for Thunderbird and for plenty of other programs.

    My FF have always 2-32 local FF2FF connections,
    same as TB has 2 local TB2TB connections.

    If process is listening on localhost ( 127.0.0.1 ) interface,
    nothing but local processes can connect to it.

    Imagine it as you extra network card,
    that is available only to programs running on your PC.

    If you monitor connections by sysinternals TCPview utility,
    always notice yourself
    what interface IP address a process is listening on.

    A typo, should be 2-3, not 2-32

    As far as I can tell, it's the communication between 'XULRunner'
    and the application, in this case Firefox.

    Because Firefox has 'XULRunner' built into the package, you can
    use it to run other applications. e.g.

    Firefox.exe -app path\to\application.ini


    One such application is 'sqlite-manager'

    http://code.google.com/p/sqlite-manager/
    http://code.google.com/p/sqlite-mana...nerApplication


    Just my 2 pence worth, but really only a guess.
