526736 - Mailto-links don't open a new window, the declared mailto-handler-site is loaded into the actual selected frame/window

Status: RESOLVED WONTFIX

(Mozilla Labs :: Prism, defect)

Description

[TCP]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; de; rv:1.9.1.4) Gecko/20091016 Firefox/3.5.4 (.NET CLR 3.5.30729)
Build Identifier: 

When I click on a mailto-link inside my application my registered mailto-
protocoll-site isn't opened in a new window, instead of that it loads
it in my actual selected window or iframe.

At first I've had the same problem with mailto-links from external
programs, but I changed the following in the "handle"-function
(components\nsCommandLineHandler.js):

"...
// Check for an existing window and reuse it if there is one
    if (win) {
      if (protocolURI) {
                var ios = Cc["@mozilla.org/network/io-service;1"]
                    .getService(Ci.nsIIOService);

                if (ios.extractScheme(uriSpec)=="mailto") {
                  try {
            var x = Math.round((screen.availWidth - 800) / 2);
            var y = Math.round((screen.availHeight - 600) / 2);
          } catch(e) {
                var x = 300;
                var y = 200;
          }
          var featureString="scrollbars=no, dependent=yes,
resizable=yes, left=" + x + ",top=" + y + ",width=800, height=600";

          var newWin = win.open(protocolURI, "NewMail",
featureString);
          //win.open
(protocolURI,"NewMail","scrollbars=no,dependent=yes,resizable=yes");
                } else {
                  win.document.getElementById("browser_content").loadURI
(WebAppProperties.uri, null, null);
        }
          }

      aCmdLine.preventDefault = true;
      return;
    }"

I've found the function where the mailto gets assigned ("newURI" in
components\nsPlatformGlue.js) but I don't have a clue what happens
after that. 

Reproducible: Always

Steps to Reproduce:
1.Register a protocol handler. For example: "platform.registerProtocolHandler("mailto", "http://www.example/mail/message.html?action=NEW&to=%s");
2.Click somewhere in your application on a mailto-link. For example "[e-mail]"
Actual Results:  
"http://www.example/mail/message.html?action=NEW&to=[e-mail]" is loaded in the actual window/frame.

Expected Results:  
"http://www.example/mail/message.html?action=NEW&to=[e-mail]" should be opened in a new window.

what is platform.registerProtocolHandler? is it an about:config pref?

I think he means navigator.registerProtocolHandler.  But this also happens one just chooses Gmail from the preferences, and presumably also Yahoo Mail, and it's really not what one would expect ...

And just to rub things in, it also loses history: see bug 499527.  (Though, uh, maybe that part's to do with some cruft in my profile; it doesn't seem to happen on a more-recently-created one.  On the other hand, having an optional "feature" to lose history when you click on mailto: links is not at all useful ...)

To make the process simpler, by default Firefox offers gmail and yahoo mail as webmail handlers. You can just go to about:preferences#applications and select it, then try clicking a mailto link. Here is screenshot of setting the webmail handler - http://i.imgur.com/UM5vQXs.png

I can confirm this behavior so marking it as "new" bug.

Prism isn't maintained anymore. Mass closing of the bugs.
