Status: VERIFIED DUPLICATE of bug 11459

(SeaMonkey :: General, defect)

Description

[Tom Jackson]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.3b) Gecko/20030210
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.3b) Gecko/20030210


When I set Mozilla to be my default browser in Edit|Preferences|Navigator, it
also sets itself as my default mail handler, 

Reproducible: Always

Steps to Reproduce:
1.Set Mozilla as default browser
2.Try to click on a link in a web page that has contains a "mailto" statement
3. XP ignores my default mail setting in MS Outlook that makes it my default
mail handler and loads Mozilla mail (regardless of whether Mozilla is loaded at
the time or not.
4.Keeps doing this until I re-set IE to be my default browser, at which time
Outlook then resumes being my default mail handler.

Actual Results:  

If I keep mozilla as my default browser XP ignores my default mail setting to
Outlook XP

Expected Results:  

Set itself as my browser and left my mail settings alone.

Try unmarking "Use Mozilla Mail as the default mail application" under
Preferences - Mail&Newsgroups.

Should work then.

Comment 2

The box in Mail&Newsgroups is unchecked.  Still happens as I described.

Comment 3

Does this also happen if you click the mailto: link in IE?  Or only in Mozilla?
 (When Mozilla is the default browser, of course.)

Comment 4

[Tom Jackson]

Good question:  when I click the mailto: link in Mozilla, it calls Mozilla 
mail regardless of whether Mozilla is the default browser or not.  At that 
time, Mozilla mail is not set as the default mail app.  In IE, IE calls 
Outlook regardless of what the default browser is and Outlook is set as 
default mail.

IE and Firebird under Windows consider the registry key 

My Computer\HKEY_CLASSES_ROOT\mailto\shell\open\command

which determines what to do with mailto-Links. Mozilla seems to ignore this
setting and always use Mozilla Mail instead to handle mailto-Links.

See also bug #56478, which might be related to this one...

[Oleg Sidletskiy]

Mozilla Mail isn't set as default, it's just that Mozilla navigator ignores the
default mail client.

Comment 7

[Mike Cowperthwaite]

Rather than make you read all of the very long and tedious bug 11459, here's how 
to fix this problem under Windows (and Mac, or so they tell me):  Set the 
Mozilla preference
   network.protocol-handler.external.mailto
to be True; and make sure the 'mailto' registry key described in comment 5 is 
set correctly.  Mozilla will then use the correct mailer for mailto links.

Bug 56478 is related, but is Linux-specific.

Verifying dupe.
