[Message part 1 (text/plain, inline)]

Hi,

When using org-export-dispatch in an org-buffer, and then pressing h
and o for opening the html file, the html is generated but not opened.

How could I please display the generated file in Firefox?

TIA for any help, Peter

Typing `o' calls `org-open-file', which checks the value of
`org-file-apps', which contains the entry `("\\.x?html?\\'" . default)',
which checks if you have a mailcap entry to handle html files, and if
you don't, it just visits the file in Emacs.  The doc string of
`org-file-apps' gives an example of how to make Emacs open html files in
Firefox, by adding a suitable entry to `org-file-apps', e.g. like this:
(add-to-list 'org-file-apps '("\\.x?html\\'" . "firefox %s"))
If you do that, you should get the result you want.

Ah, thanks. My mailcap is
text/html; w3m -T text/html -dump %s; copiousoutput

That’s why it wasn’t opened...

Thanks, it works well!
