272625 - When Mozilla is set to the default browser, it does not set HKEY_CLASSES_ROOT\mailto\shell\open\command

Status: RESOLVED DUPLICATE of bug 202497

(SeaMonkey :: General, defect)

Description

[Dan Roca]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X; en) AppleWebKit/125.5.5 (KHTML, like Gecko) Safari/125.11
Build Identifier: Thunderbird 0.9 and Mozilla 1.7.3

When Thunderbird and Mozilla is set to the default browser, they do not set 
'HKEY_CLASSES_ROOT\mailto\shell\open\command' so that mailto links are properly handled by the 
default mail client. Both Eudora and Outlook set this registry setting as well as the 
'HKEY_LOCAL_MACHINE\software\clients\mail' setting.

Reproducible: Always
Steps to Reproduce:
1. Install Mozilla or Thunderbird
2. Set it as the default mail client
3. Check 'HKEY_CLASSES_ROOT\mailto\shell\open\command' mail in the registry
Actual Results:  
The registry setting does not change. This will cause many applications to use whatever was last set in 
that registry entry to be used as the mail client instead of Mozilla or Thunderbird.

Expected Results:  
Mozilla and Thunderbird should set the 'HKEY_CLASSES_ROOT\mailto\shell\open\command' to itself so 
that Mozilla will be used when mailto links are passed to the OS.

My bad - this only happens on Mozilla 1.7.3 and not on the latest Thunderbird (0.9) - I thought I was 
using the latest, but I wasn't. 

It's still an issue for Mozilla, but not for Thunderbird.

Default browser is not the same as default mail client. So have you set Mozilla
as  default mail client? 
see Edit - Preferences - MailNews: [x] Use Mozilla as the default mail appl.

Yup - try it for yourself. I set Mozilla Mail to be the default Mail client. It didn't touch 
'HKEY_CLASSES_ROOT\mailto\shell\open\command' to Mozilla. 

This was reported by one of our (Meeting Maker, Inc.) large customers in Netscape 7.2 and it still exists 
in Mozilla 1.7.3, but appears to have been fixed in Thunderbird 0.9.

I conform this bug.
I am using Mozilla Suite 1.7.3 on Win2K SP4.

I checked the option "Use Mozilla Mail as default mail application" and no
matter how many times I do it, MS Outlook opens whenever I click on a mailto link.

I also Selected Mozilla Mail as default mail application uner Control
Panel->Internet Settings->Programs. Still no use.

Also I cheked the registry values specified. First (HKCR) refers to Outlook and
second (HKLM) doesn't contain any path to Mozilla mail.

Dan, 1.7.3 is actually pretty old (9 months or so).  Is this a problem with a
current trunk Mozilla build?

Comment 6

[Dan Roca]

Yeah, the bug is still currently in the latest build of Mozilla (1.7.5). 

Comment 7

[Boris Zbarsky [:bzbarsky]]

Dan, the latest build is 1.8a5, and will soon be 1.8a6.  Could you please test
that?  1.7.5 is just 1.7.3 with security updates...

[Dan Roca]

Ugh.  Even though none of your users use the nightly builds or tester builds, I tried it on that one 
(1.8a5). And even though the bug is really easy to rep - I went to the trouble of installing 1.8a5, testing 
it, and then going back to install 1.7.5 (I don't use beta builds of mozilla if I can help it). 

The bug is still there. It's there in the official build (1.7.5), it's there in the latest tester build (1.8a5), 
and it's there in the latest nightly build (as of 2004-01-10-07).
