What is this about?

In the last few days I've been getting this error message in Thunderbird
even though I have bot change any setting in it, just like I have not
changed my Chrome's cookie settings. Very annoying.

"You've reached this page because we have detected that cookies are

I assume you've clicked on a link in Thunderbird. If so, the message
merely means that the page you wanted to see won't open until you enable
cookies.

Nope. I did not click on a link, but now I wonder if I should also
enable 3rd party cookies. Somewhere I read that those should not be enabled.

Thunderbird is, at heart, a web browser.

90% of the files in the source tarball, are source
files for a browser. There's a copy of Firefox in
the Thunderbird source.

If this was happening to me, I'd be using a copy of
Wireshark, to capture what packets Thunderbird is emitting
when it starts. It *could* be trying to reach the mozilla
web site and get the source code for the teaser window
for when it starts. But it could just as easily be
going to some unexpected site, in which case you'd
want to make sure the profile didn't contain
compromised information.

If you don't like Wireshark, a less effective tracing
tool would be TCPView.

Chrome is malware. Those are "tracking" cookies. They tell Google
the sites you visit so they can place certain ads (depending on
your types of interest.
And one cannot remove all of Chrome once it has been installed
(except possible via "safe mode" which I haven't tried).

THunderbird is a web browser.

The main windows is drawn based on some XML file.

When THunderbird starts, it can put Mozilla advertising
in the lower-right pane. THis requires contacting a
known address on the Mozilla site, and picking up version
specific advertising material.

Download TCPView and start it. It shows connections opening
and closing.

Now, double click the Thunderbird icon to start Thunderbird.

Glance over at the TCPView window. Did a new connection open ?
Is the connection to Mozilla or to some other web server ?

When the web server is contacted, all the normal things happen.
If they craft poorly designed web code, it could be that
the Mozilla advertising page is trying to track access by
setting a cookie on the client. Note that cookies are seldom
implemented as actual (old-fashioned) cookie storage any
more. The web page attempts to use DOM storage instead, and
the browser has all sorts of cracks and crevasses to store
identify information. When a diagnostic message says
"I cannot store a cookie", that's not really what it
means. It means "your DOM storage is not working for
me, or I am unable to abuse your browser the way
I expected", rather than a puny cookie being denied.

I always leave cookie storage *wide open* and I
still see that stupid message. I get a chuckle out
of this, that the message complains about cookies,
yet my cookie storage is there is they want it.
But they don't use it, because I would only
erase the cookie at my next convenience :-)

You can fix this problem one of two ways:

1) Discover that the web communication is illegitimate
and track down how that is happening.

2) Discover the communication is normal (such as the
advertising page picked up at startup), then make sure
that the browser policies are open enough to cause
the error/warning message to go away.

The usage of TCPView or the usage of Wireshark, are
to try to provide some information about what
Thunderbird is trying to contact. Even some third-party
firewalls could help you, and perhaps you are more
familiar with using such outgoing firewalls for
discovery or research purposes. (I.e. Zonealarm
could tell you that Thunderbird is trying to contact
"some" site.)

Really, Paul??I understood Thunderbird was the e-mail program that grew
out of the Mozilla Suite. Sure, Thunderbird contains much of the (Gecko)
coding required to Compose and/or display received e-mails that may
contain HTML ... but, at it's roots, Thunderbird is still an e-mail
agent!! Isn't it??

A suite works, because the "source sharing" is kinda hidden.

Once you "part out" Thunderbird as a separate source tree,
your knickers are exposed. If you're using the engine from
the browser, somehow you have to link to that. And since the
browser portion may need "tweaks" to meet project objectives,
that means eating the whole source tree. For better or worse.
For example, if the browser portion invaded privacy, maybe you'd
have to turn off parts of it.

The source tree is *way* too big, to do any sort of analysis.
Even running a debugger (WinDBG with IDE integration), I
tried that once with Firefox and it was hopeless. After
two hours of single stepping stuff, I got no-where fast.

https://en.wikipedia.org/wiki/Histor...la_Thunderbird

Thunderbird Version (Gecko Version) Based on Firefox version number
------------------- --------------- -------------------------------
...
Thunderbird 52 52.0 52.9.1 [ XUL ? ]

Thunderbird 60 60 60 [ "new method" ]

The Thunderbird .mozconfig file had a build option to just build the
browser portion. As a means of proving the pouring of the
source tarball, into the Tbird source tree, didn't break
anything.

I build these programs occasionally. I've built Thunderbird,
Firefox, and Chromium from source. Some of these efforts
take a couple days of solid effort, and 5GB+ worth of download.
The build recipes aren't completely honest and above
board (you download a tarball, but can't use it, and
have to clone an HG tree instead, filled with 50% more
third party files like Rust and friends). If you do want
to try your hand at building, use an x64 OS and own
a big machine (even if the executable is x86). A machine
with 3GB of RAM isn't nearly enough now. Even a 16GB machine
is too tight during the linking phase (the linking phase can
be done as one giant obj loading exercise, and basically every
object compiled, gets linked at the same time. Memory
usage during that step, shoots through the roof, and
is the "rate limiting step").

I generally split my machine, put the source tree in
a 32GB RAMDisk, and leave the other 32GB for the OS and
tools to use. That usually works OK.

The developers who work on projects like this, use
20-core computers. And probably as much RAM as you
can stuff into such machines. My machine isn't that big :-)
You won't find any developers there running a Core2 Duo
and 3GB of RAM. That ship sailed years ago.

Paul's comment "Thunderbird is, at heart, a web browser." is (IMO)
not quite correct. Thunderbird contains an HTML renderer, which can also
render remote content / webpages, but that's not the same thing as a
web-browser.

Thunderbird and Firefox share a large part of the HTML renderer code,
but Thunderbird is still only an e-mail (and NetNews) client and Firefox
is still only a web-browser.

Sadly, they use their turn-it-on-and-the-lights-dim machines not just
for compiling, but also for testing. So they have no (OK, little) idea
how their code actually _runs_ on lesser machines.

Function (email client) and architecture (method of displaying content)
are two different things. Keep in mind that a mail server is just a
server that stores mail. "Web pages" are just different content, is all.

If someone were to send me a web-page, rather than a link to the
web-page, sure, TB would display the content of the e-mail, which would
appear as a web-page ... with-in the e-mail program!!

Is that what you mean by "remote content", Wolf??

NB that Tbird can display "remote content" if you permit that. That's
web pages. Web pages usually include or link to trackers these days.
Tbird's option protects you from tracking, if that's what you wish.

I suspect that OP's Tbird is set to d/l remote content without first
requesting permission. Check Tools - Options - Privacy - Mail content -
"Allow remote content..." and change as* desired.

Best,
