[Bug 557640] Re: [Lucid Beta2] nrf-003 testcase failed Default "Welcome to Ubuntu" page doesn't appear without connectivity

[Chris Coulson]

What is happening here is that as Firefox is starting, something
initializes nsIOService before libdbusservice.so has registered
nsNetworkManagerListener. Because there is no compreg.dat at this state,
nothing provides NS_NETWORK_LINK_SERVICE_CONTRACTID at the point that
this code section is executed in nsIOService::Init

    // go into managed mode if we can
    mNetworkLinkService = do_GetService(NS_NETWORK_LINK_SERVICE_CONTRACTID);
    if (!mNetworkLinkService)
        mManageOfflineStatus = PR_FALSE;

    if (mManageOfflineStatus)
        TrackNetworkLinkStatusForOffline();

So, from this point, Firefox does no tracking of the network
connectivity and nsIOService::GetOffline always returns FALSE (which is
what ubufox is using to get the network status).

When you run Firefox for a second time, calling
do_GetService(NS_NETWORK_LINK_SERVICE_CONTRACTID); from
nsIOService::Init triggers loading of libdbusservice.so and automatic
registration of nsNetworkManagerListener, because it exists in
compreg.dat from the previous run

XPCOM component registration has changed quite a lot in Firefox 4.0, so
I suspect this might not be an issue there.

This isn't going to be fixed in Firefox 3.6.
