Whoops. I should have read the page better.

However, clicking on that button in icecat does not send E-Mail for me. 

Monitoring the network interface I can see that it redirects to a mailto: URL. So that's nice.

Checking the application preferences of icecat, it only gives "always ask" (note: it doesn't ask) and not an application for "mailto". (in GuixSD)

Creating my own HTML page with a mailto link doesn't work either.

Therefore, I reported a bug to Guix too.

Bug report follows:

"mailto:" links don't work in icecat.

Checking the icecat source code, there are several ways to handle E-Mail. One of them is as "external helper app". One of those (not sure whether it's the correct one) uses gio's g_app_info_launch_default_for_uri in order to launch helper applications.

There is a test icecat-38.8.0/uriloader/exthandler/tests/unit/test_handlerService.js that does:

  let isLinux = ("@mozilla.org/gio-service;1" in Components.classes);
  if (isLinux) {
    // Check mailto handler from GIO
    // If there isn't one, then we have no mailto handler
    let gIOSvc = Cc["@mozilla.org/gio-service;1"].
                 createInstance(Ci.nsIGIOService);
    try {
      gIOSvc.getAppForURIScheme("mailto");
      noMailto = false;
    } catch (ex) {
      noMailto = true;
    }
  }

And this ./toolkit/system/gnome/nsGIOService.cpp uses g_app_info_launch_default_for_uri .

Therefore, I tried it out:

#include <glib.h>
#include <gio/gio.h>
#include <stdlib.h>

int main() {
        GError* error;
        g_app_info_launch_default_for_uri("mailto:foo@example.com", NULL, &error);
        // g_app_info_launch_default_for_uri("http://www.google.at/", NULL, &error);
        if (error) {
                g_warning("err %s", error->message);
                g_error_free(error);
                return 1;
        } else
                return 0;
}

I get:

** (process:12464): WARNING **: err Operation not supported

If I debug it some more I get:

There would be g_app_info_set_as_default_for_type () to set a new default application in nsGIOService - which is exposed and used by ./browser/components/shell/nsGNOMEShellService.cpp on setting icecat up as default browser (so not always).

I'm using Fluxbox.

If I click the reply via email button in Icecat, it switches to icedove 
but does not open a reply email at all.
In ungoogled-chromium, it opens up a blank reply email, failing to fill 
the To, CC, Subject with anything.

If I click the equivalent mailto link on the issues page in Icecat, its 
the same
If I click the equivalent mailto link...., but in chromium, it opens a 
new email, but only the Subject is filled out. No To or CC.

I've always thus replied to the mailing list by manually copy-pasting 
the the Subject, adding Re:, and trying to find the posters email 
address, and bug address to add in To/CC. Is this related to your bug?
