For a couple of weeks now, I've been compiling a list of the remote IP
addresses which Firefox connects to automatically at program startup. My
goal is to completely stop FF from doing this or at least to understand
why it's calling out to these addresses. I realize that some of these
callouts may be due to the extensions I use, also realize that there are
various IP ranges which FF connects to so that this list is going to be
incomplete. Regardless here is the list:

Note that 443 is a secure port.

52.24.25.164:443 (Amazon Technologies Inc.)

Towards the end of quieting down Firefox, I've noticed this discussion
in the Wilders Security Forums:

Comments?

TIA.

If you are using the protection against malware sites and phishing
sites, the browser would make contact with Google to update the
blocklists. If you have no feeds, I cannot think why you would be
connecting with Amazon or EdgeCast.

Do you keep cookies?
My FF 27 and SM 2.26 do not call out upon startup.

Thanks for replying!

No, although I have:

"Query OCSP responder servers to confirm the current validity of
certificates" checkmarked

that shouldn't cause any calling out at startup because I have my home
page set to about:blank.

In addition, I also have:

-Both "Block reported attack site" and "Block reported web forgeries"
unchecked in Options
-"Never check for updates(not recommended, security risk)" checked
-Search Engines Automatically Update unchecked
-No Sync account
-All Data Choices (Telemetry and Crash Reporter) unchecked
-As I've already mentioned, I'm not subscribed to any Live Feeds as far
as I know. However, I don't know of any way to find out for sure if this
is the case other than to manually go through each of my almost 1000
bookmarks. Still, I have no recollection of ever subscribing to any.

As far as extensions, I use the following which update certain
components (eg. AdBlock Plus filter subscriptions) separately from
Firefox update:

AdBlock Plus ("Automatic Updates" set to "Off", "Count Filter Hits"
unchecked, "Sync Adblock Plus Setting" unchecked
Copy Link Text ("Automatic Updates" set to "Off")
Download Panel Tweaks ("Automatic Updates" set to "Off")
Ghostery (but I have Ghostrank and "tracker library auto-updating" both
unticked)
Link Visitor ("Automatic Updates" set to "Off")
Video DownloadHelper ("Automatic Updates" set to "Off")

Shockwave Flash plugin is set to not check for updates.

I've gone into about:config, filtered on "url" and removed some of the
website address values from various preferences.

In short, I've literally spent hours trying to block firefox from
calling out at startup and my efforts have failed.

The problem I see here is that there's no reference website which
explains why various IP addresses and IP address ranges are called by
Firefox and that Mozilla doesn't require extension authors to provide
information about which IP addresses and IP address ranges (if any)
their extensions will want to be contacting.

Without that information, it's impossible in many cases to make informed
choices about whether or not you want such connections to be made by
Firefox and any extensions you use. Also, determining whether or not
malware is making such connections is made far more difficult.

In addition to all this, I want to stop Firefox from starting
wmiprvse.exe at startup (I'm still using XP MCE SP3 for my OS.) But
that's a topic for another thread.

I keep a few select cookies, but AFAIK, cookies aren't responsible for
Firefox calling out at startup.

I agree with your frustration that such information isn't available.
However, a brute force method would be to block them anyway, and just
see if anything (Firefox and the add-ons you have) breaks. I use the
ancient Kerio as a firewall, and that allows me to block accesses by
what application is calling them, by address, by port, by direction, and
by protocol (in other words I can block Firefox, in and/or out, TCP
and/or UCP, to an address or address range, any or specific ports). I
_presume_ more modern firewalls can be configured to do similar.

Not knowing what that does, and/or whether when you _do_ want to start
it you do it from within something else that has it hard-coded or
whether you start it by command line or shortcut that could be modified,
my immediate reaction of changing its name may or may not be valid.

Looking into this on a linux machine, the only calls that I get in
the start up of a fairly clean FF install, with only a few plugins
and no extensions are:

count IPnumber hostname

2 54.192.144.224 -- self-repair.mozilla.org
4 72.21.91.29 -- ocsp.digicert.com
2 173.194.121.4 -- safebrowsing.google.com / clients1.google.com
1 173.194.121.7 -- safebrowsing.google.com / clients1.google.com
2 173.194.121.9 -- safebrowsing.google.com / clients1.google.com

[both the google and mozilla names resolve to multiple ipnumbers so
what you trap (off a router) will vary based on their DNS A-record
shuffle.]

If I turn off the "block reported attack sites" and "block reported
forgeries" options under preferences/security I don't get the calls
to google on startup.

So, I would conclude that most of what the OP is seeing is from
extensions. If you're concerned by their "calls", turn them off.

Not trying to be too snarky here, but if you're running in a MS
environment, FF and related calls are probably the least of your
worries. The blast of DNS queries on my network from MS machines on
startup (and ongoing) -- looking for MS and OEM sites -- is never
ending.

[if you want something to be concerned about ... look at the
continuous spew of outbound connections from all your mobile
device's apps! [but that's not a discussion for this list.]]

Yes, I should fire up Wireshark before starting Firefox and see what I get.

To be fair, I've also stopped getting callouts to Google since I did
likewise.

I believe it. However as I said, I'm using XP and I don't believe that
it does this as much as newer versions of Windows.

I don't use any mobile devices. Don't even have a cell phone, never have
and never will.

It's unique to XP. Moz developers want to run wmiprvse.exe for
diagnostic info. Since I've turned off both Health Report and Crash
Reporter, there's no reason for wmiprvse.exe to be run. I know I could
probably remove the code which is responsible and recompile FF, but the
code would reappear with the next update.

I have seen a lot of text re: this call out issue. A main reason that I
use open source software is the perception of honesty on the part of the
software creation organization. I feel that I can trust them. I don't
question upgrades like I did with Microsoft. Now we seem to have an
issue of possible deception and underhandedness (must be a word-it
passed spell check). We need an official response from Mozilla. In the
spirit of open source, we should have the clear option of turning it
off. I believe that the ONLY time that a browser (a receiving program,
not a sending program) should send anything out is for diagnostic
reasons, which I turn on (see "trust" above).

As I indicated in an earlier message, the "callouts" that the OP is
seeing seem to be from extensions that he has (optionally)
installed. They do not appear to be from FF core.

Analyzing my router and DNS server traffic, all I get from my
(linux) FF are:

count IPnumber hostname

2 54.192.144.224 -- self-repair.mozilla.org
4 72.21.91.29 -- ocsp.digicert.com
2 173.194.121.4 -- safebrowsing.google.com / clients1.google.com
1 173.194.121.7 -- safebrowsing.google.com / clients1.google.com
2 173.194.121.9 -- safebrowsing.google.com / clients1.google.com

The google "calls" go away if you turn off the "forgery" and "attack
site" selections under preferences/security. I didn't muck with my
certificate settings to see if the digicert.com ones would go away.

Anyone who is bothered by the two "calls" to self-repair.mozilla.org
can look at the source:

<ftp://ftp.mozilla.org/pub/mozilla.org/firefox/releases/latest-beta/source/>

Are you officially connected to Mozilla? Is this an official comment by
Mozilla? If so, you should ID yourself as such.

Additionally, an official comment like "Firefox, with no "extensions" or
modifications, does not send any data from your computer anywhere except
for diagnostic data that we clearly describe, and give a clear
opportunity to block." would be a good response to this dialog.

I am not associated with mozilla, and did not in any way indicate
that I was. As I thought was fairly clear, I simply did analysis in
my linux environment, and really don't see any "call out" issues
with my extension-free install. You can do your own analysis,
including packet inspection and source code review, and come to your
own conclusions.

[please keep the posting order consistent so that the thread remains
readable.]

You can turn off that stuff. You can disable telemetry, health report,
geolocation, you can disable automatic updates, the protection against
fake sites and malware sites, and not subscribe to feeds. If you
dislike the idea of peer connections turning on your microphone or your
webcam, you can disable that. You can also use about:blank as your home
page.
If the settings will not stay put, you can copy them into a user.js file
to force the issue.

Hi John, as you, I have been monitoring firefox instance from a blank startup page. And i got interesting reports.

First i've to say that i'm not a developer, so probably i miss a lot of things.

Well, in a first try, disabling all checks for updates, all blocking web sites list and health report and those staff, i detected mainly two ip address , Amazon, Edgecast. after a few seconds firefox started with a blank page.

Inspecting packets was my following step so i discover was certificates /OCSP related, so i decided to turnoff OCSP validation.

I think automatic callouts will dissapear with this, but still there to the same ip addresses.

I inspected again packets involved on these conversation and saw the "repair.mozilla.org" entry in th packet, so i searched in about:config tab in firefox and deleted th address, restarted firefox and now no automatics callouts from firefox.

PD.I think OCSP is recommended to enable again.
Bye.
