--------
View "text/html" parts of the current article with a WWW browser.
Inline images embedded in a message using the cid scheme, as they are
generally considered to be safe, will be processed properly.
The message header is added to the beginning of every html part unless
the prefix argument ARG is given.

If you always want to display HTML parts in the browser, set
‘mm-text-html-renderer’ to nil.
--------

Setting (setq mm-text-html-renderer nil) works, but it will open *all*
mails in the browser.

So I tried with a local variable:

--------
(defun my-gnus-article-browse-html-article ()
  ""
  (interactive)
  (let ((mm-text-html-renderer nil))
    (gnus-article-browse-html-article)))
--------

-> this blocks ("waiting for external displayer to die...")

Next I tried:

--------
(add-to-list 'mm-text-html-renderer-alist
             '(ff . browse-url-firefox-new-tab))
(defun my-gnus-article-browse-html-article ()
  ""
  (interactive)
  (let ((mm-text-html-renderer 'ff))
    (gnus-article-browse-html-article)))
--------

-> this gives an error like
shell-command-to-string: Wrong type argument: characterp, #<buffer
*mm*-455001>

Finally I tried to create a new thread to get around the blocking
problem:

--------
(defun my-gnus-article-browse-html-article ()
  ""
  (interactive)
  (make-thread
   (lambda ()
     (let ((mm-text-html-renderer nil))
       (gnus-article-browse-html-article)))))
--------

This works better than the first solution, but it doesn't work perfectly
(blocks for some seconds, saves the mail multiple times and opens it
multiple times in the browser).

Any idea?

Thanks and Best Regards,
