No.

You can ask the LLM-AI questions like this, and it will
tell you how the software works, as the software is open
source, and the LLM-AI can actually read the source files.

Firefox ----+ \
Firefox --+ \___ The parent process, talks to its children [Quantum]
Firefox -+ /

<=== This air gap exists between the two process sets
Notice there are no plus signs here, no path.

Thunderbird ----+ \___ The parent process, talks to its children [SuperNova]
Thunderbird -+ /

When Thunderbird is asked to open a URL in a Firefox window, it does it like this.
Firefox may not even be running at the time, and if it is not running, then
it starts up (Process Create does this). For security reasons, the functions the programs carry out are limited, as part of controlling the attack surface. They don't arbitrarily lash a bunch of shit together in a careless manner. When Thunderbird does this, it can even call the Default Browser, which may not even be Firefox.
It could end up calling up MSEdge this way, if MSEdge happens to be the users choice of Default Browser. So while I draw it like this, other From-To pairs can exist.

Thunderbird --\
\
OS (Process Create with a passed URL as a command line parameter)
/
(Firefox) <---/ [this could be any web browser on the system...]

The designers look for common features on the OSes, before defining mechanisms for communications. The staff at Mozilla don't like writing custom spooky code for each OS, but things like the graphics stack are an example of an exception. Graphics, and I would suppose Printing, could involve extra effort to support three or more OSes.

Did you probe into this before answering?

Or did you just make clueless claim? :)

You mean, like the strawman proposed by this discussion thread ?
That would be a clueless claim.

Why don't you ask the LLM-AI whether this is how it works
or not ? Since you don't trust a human to answer your question,
make friends with an LLM-AI and have the LLM-AI explain the
rules a little bit.

Why would they want/need to?? I mean one's a Browser, the other's a Mail
and Newsagent.

Thunderbird still has Browser code in it.

Settings > General > Thunderbird Start Page
[*] When Thunderbird launches, show the Start Page in the message area

I just put craigslist in there

Sorry! What "Start Page"?? It just shows a screen with your various E-
Mail and News accounts, doesn't it??

Not a start page per se opening in a browser...just loads the web page
url in the message pane window. Clicking on a message in the mail or
news in the message list replaces the loaded url in the preview window.

The loaded web page may have active links to open the default browser.
- i.e. Thunderbird does not automatically open FireFox(both Mozilla
based), it opens the Windows configured default browser when an active
link is clicked/opened.
