Some web browsers support passing mailto: links to various webmail
providers. It would be good to have a MUA option for each of these web
browsers so folks can send bug reports via their preferred webmail MUA.
At minimum Firefox and Chromium should be supported, but I've started a
discussion about which browsers support mailto: for webmail providers:

Hi,

Recent versions of reportbug have semi-experimental support for xdg-email,
which sends a mailto: URI to whatever the user's configured handler is. Would
that cover this case? I guess there might be two steps, and I'm not sure if
browsers cover them both:
 * setting a webmail provider as your mailto: handler within the browser
 * system-wide/xdg setting that browser as your mailto handler, since it knows
how to open the webmail

If browsers don't take care of step #2, it could probably be done with
xdg-settings set default-url-scheme-handler mailto firefox-esr.desktop

and the foregoing would benefit all programs and is not reportbug-specific.

These bugs are for two different features, please don't merge them.

As I already discussed with Nis Martensen, the existing support isn't
sufficient. Since this discussion was unfortunately not CCed to any
bug, I have attached it to this mail. See also this feature request:

https://bugzilla.mozilla.org/show_bug.cgi?id=1653821

I now see the difference in the titles—965303 is for viewing existing reports—
but your text still described report sending, I thought you'd sent it twice:

No, they are both about bug report composing/sending, in different contexts.

I have started working on a branch for these two features:

I got distracted by various other things I found while looking at the
code, so there are some other things mixed in for now.
