    Since I use Firefox 1.0 Pr, I noticed the following problems:
    1) when I leave my desktop unattended with FF open, Zone Alarm never
    engages the lock nor my modem automatically shuts the connection, as it is
    supposed to. Why ?

    2) using netstat as soon as I start Windows, without even opening FF and
    before I get an Internet connection,I get:

    Active Connexions

    Proto Local Adress Remote Adress State
    TCP mycomputer:bnews www.net-ful.com:0 LISTENING
    TCP mycomputer:500 www.net-ful.com:0 LISTENING
    UDP mycomputer:rscs0 *:*
    UDP mycomputer:sytek *:*

    What's all this ? "www.net-ful.com" was included in an HTML page of a
    newspaper on-line I read sometimes. I searched for *.* containing "www.net-
    full.com" on my HD, but found nothing. Where does it come from and how can
    I stop it. Do I have a Trojan ?

    3) I surf in tabs. It seems FF opens a new port each time you open a new
    tab. However, it never closes any, even when you close FF window. does
    anybody know if this is specific to the preview version ?

    Ron,

    The reason that zonealarm doesn't close the connection is because
    Firefox has in internet "keep alive" mechanism. If you wisht to turn it
    off do the following:
    in the address bar type "about:config" which will list a list of
    settings. Look for "network.http.keepalive" change that to false.

    as for the second part, i don't think it's related to firefox.
    perhaps you've got some spyware on your system? try using ad-aware to
    clean it up. if it's not spyware, do you have any memory resident
    programs running?

    Thanks Swavek. I played around with "keepalive" and "timeout" parameters. I
    have been able to have Zone Alarm lock work normally. My modem connection
    never stops however. But maybe it is a modem problem ?

    For the second part, I always use Adaware and Spybot. But I just noticed
    there is a new version for adaware, and I am downloading it. I'll keep you
    informed should it find anything !

    There is an option for a dial-up connection to disconnect if it idles
    for too long. You can enable that if you'd like which could be what
    you're looking for. There's nothing wrong with your modem connection.

    i haven't used spybot but i've used ad-aware many times and it often
    seems to miss a critical area in the windows registry.
    open the registry editor (regedit.exe) a navigate to:
    hkey_local_machine\software\microsoft\windows\currentversion\run (click
    on run)
    look at the right pane. examine that list of programs for anything
    suspicious. these program that run at start-up.
