Yahoo Mail mailto (web protocol) handler is broken (

The Yahoo Mail web protocol handler, accessed when mailto is set to "Use Yahoo Mail" in Applications, appears to be broken.  The entire mailto: URL is ending up in the "To" message field, rather than being parsed as expected.

1. Log into Yahoo Mail
2. Go to
3. Open File->Send link
4. A new message is composed, with "mailto:?body=" in the To field.
Is Yahoo aware of this issue?  This works as expected for Internet Explorer users.
Whiteboard: [parity-IE]
I don't believe they are, as this was working when we launched 3.0, but it looks like there's been a change in handling since it was implemented, as it's definitely broken for any complex mailto's (essentially anything that has more than a to: and cc:). Is ctalbert's mailto testcase part of the general testing we do?

I'll reach out to the Y! mail team on this.
The Yahoo! Mail team is aware now, and has confirmed they're seeing the same thing we are. They're looking into it, and I'll update the bug when I have more info.

i am copying over from bug 530616:

set options->applications->mailto to yahoo mail
file->send link

this gives in the NEW yahoo mail:
to: (empty)
cc: (empty)
subject: (empty)

and in CLASSIC yahoo mail:
to: mailto:?body=
cc: (empty)
subject: (empty)
body: (empty)

should be (as it works on gmail):
to: (empty)
cc: (empty)
subject: problem sending link with yahoo mail • mozillaZine Forums

We don't have a blocking flag on this bug, so adding [3.6+] to the whiteboard.
Whiteboard: [parity-IE] → [parity-IE][3.6+]
so is this supposed to block?
It can't block if it should be fixed by the Yahoo team but the parity-IE flag suggests otherwise.  Beltzner, can you move it to the right component if Tech Evang isn't it?
They are working on it, and agree it's broken. No ETA on a fix, though.
i just tested it on Mozilla Developer Preview 3.7a1
yahoo classic mail does not even open a new message, just stays on the main page.
may we change the product from "tech evangelism" to "firefox" so we may request blocking of 1.9.3?
beltzner added [3.6+] to the whiteboard at the time, but that did not seem to help...

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.3a1) Gecko/20100208 MozillaDeveloperPreview/3.7a1 (.NET CLR 3.5.30729)
I think this remains an evangelism issue, as the UA parsing by Yahoo! is the issue here, not that the mailto protcol handler is broken for the preview. worse end result, but a different problem.

I'll ping the folks I know, as this could bite us in the behind later. I just wish the UA detection actually did use "and higher" logic.
i think at this stage we should reverse engineer the issue, to have an in-house solution for version 4.
disagree. changing the product to deal with a broken web service seems like the wrong way to do things.

Should we consider removing Yahoo! Mail from the list of defaults? I'll ping the Y! Mail team again and ask if there's any ETA for a fix, but if it's not going to support mailto's properly, we should remove it from the list.

in yahoo NEW mail, body is now correct. title is still missing.
no change for yahoo CLASSIC mail
Is this bug a duplicate of bug 426260?
There is an open source program for Windows called Gmail Default Maker.  Despite the name, it works with other services including Yahoo.  Its purpose is to allow a webmail composer to be the default mailto handler.

I have tried it with both the Classic and newer Yahoo, and it works perfectly with both.  In Firefox, I selected File/Send Link.  A new tab opened with a Yahoo login screen.  When I logged in, a composing screen opened with the subject and body populated exactly as they should be.

As I said, the program is open source.  So it seems reasonable that you could review the code amd figure out what they are doing right that the internal Firefox function is doing wrong.

The program's home page is:
yahoo new mail now works fine for both title and body
yahoo old mail opens in inbox and does not open the mail composer at all
Version: unspecified → Trunk

Yahoo have started popping up a prompt to add a mailto protocol handler. Some people have no idea what the message means and refuse to click the "Add Application" button. They then complain that the message pops up every time they open their inbox.

Please replace the existing entry with the one provided by Yahoo. Below is the information as added by the aforementioned prompt.


On a related note, 6 YEARS wasn't enough time to add an icon to the Yahoo! Mail entry?

For what it's worth, I'm getting connected to a different server:

I'm not sure we know the most universal address for Yahoo mail (other than the classic redirector).

I suppose there's even more difference when it comes to non-English Yahoo sites, so the suggestion at comment 19 may be a dead end. I filed a separate bug report for the issue of annoying "Add Application" prompts:

The original issue here is fixed, emailing a link it displays properly in Yahoo mail now. The other issue described is being tracked in bug 668577. Closing this bug.

I'm pretty sure that Yahoo! will not fix the old UI of Yahoo! Mail as they invested time into developing the new one. I'm asking our contact at Yahoo!

But do not keep your hopes high.
