-> "view %s" mailcap-prefer-mailcap-viewers ;; -> t (setq mailcap-prefer-mailcap-viewers nil) ;; -> nil (mailcap-mime-info "text/html") ;; -> "/usr/bin/firefox-esr %s" I expect the result of mailcap-mime-info to be "/usr/bin/firefox-esr %s" when mailcap-prefer-mailcap-viewers is t because the doc of that variable says If non-nil, prefer viewers specified in ~/.mailcap. If nil, the most specific viewer will be chosen, even if there is a general override in ~/.mailcap. For instance, if /etc/mailcap has an entry for "image/gif", that one will be chosen even if you have an entry for "image/*" in your ~/.mailcap file. and $ cat ~/.mailcap | grep '^text/html' text/html; /usr/bin/firefox-esr %s; description=HTML Text; test=test -n "$DISPLAY"; nametemplate=%s.html What do you think? If you agree this is a bug, I could provide that a bisect session gave me that it started to behave this way by commit 7e47d44da4b54c518c5e09b4f3d58dafdd43033d Before that I think I got "/usr/bin/firefox-esr %s" by default. It was after a rebuild of emacs I noted a difference using notmuch trying to view some html part in external viewer. In addition I am confused why mailcap-mime-info produces "view %s" in any case because $ cat /etc/mailcap | grep '^text/html' text/html; /usr/bin/sensible-browser %s; description=HTML Text; nametemplate=%s.html text/html; /usr/bin/firefox-esr %s; description=HTML Text; test=test -n "$DISPLAY"; nametemplate=%s.html text/html; gnome-builder %s; test=test -n "$DISPLAY" text/html; /usr/bin/w3m -T text/html %s; needsterminal; description=HTML Text; nametemplate=%s.html text/html; /usr/bin/w3m -I %{charset} -dump -T text/html %s; copiousoutput; description=HTML Text; nametemplate=%s.html I would naively think that the above would result in sensible-browser maybe.
