Ah, ok, I missed the w3m part (shr works better for me), and then got
confused about what wasn't working for you, sorry!

Yes, that is very odd, it works "out of the box" for me.

Oh, wait, how do you start Emacs? I have a vague memory that there might
still be parts that check for X once, and then never rechecks, meaning
that you get different behaviour if you start a Emacs as a daemon in the
background without X, or from an Emacs that starts up with an X window.

Could that be it?

I.e. to check, stop Emacs completely, start Emacs in X, read an HTML
email, press K H?

If not, my next step would be to M-x edebug-defun on
gnus-article-browse-html-article and gnus-article-browse-html-parts and
then step through them and see what happens.

It looks like the latter ends up calling browse-url-of-file, so you
might want to experiment with that one, to see if it opens Firefox when
called on a file - if not, then that's a clue.

E.g. if you in a *scratch* buffer evaluate:

  (browse-url-of-file "test.html")

do you then get a Firefox window trying to open test.html?

If not, is your value of:

,----[ C-h v browse-url-browser-function RET ]
| browse-url-browser-function is a variable defined in ‘browse-url.el’.
| Its value is ‘browse-url-firefox’
| Original value was 
| ‘browse-url-default-browser’
| 
|   This variable may be risky if used as a file-local variable.
|   You can customize this variable.
|   This variable was introduced, or its default value was changed, in
|   version 24.1 of Emacs.
|   Probably introduced at or before Emacs version 20.1.

| Documentation:
| Function to display the current buffer in a WWW browser.
| This is used by the ‘browse-url-at-point’, ‘browse-url-at-mouse’, and
| ‘browse-url-of-file’ commands.
| 
| Also see ‘browse-url-secondary-browser-function’ and
| ‘browse-url-handlers’.

I don't think this functionality has changed a lot recently.
