Status: RESOLVED DUPLICATE of bug 209484

(Firefox :: General, defect)

Description

[Stephen Brooks]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.6a) Gecko/20031009 Firebird/0.7+
Build Identifier: Mozilla/5.0 (000000000; 0; 000 000 00 0 000000; 00000; 0000000) Gecko/20031009 Firebird/0.7+

Firebird won't open up a message window in default email client when I click on
a hotlink (email address) from current Firbird window or when I click on a
hotlink in text (URL) of Thunderbird (0.3 RC2) It opens up an error notice in
both situations.

Reproducible: Always

Steps to Reproduce:
1.In Thunderbird, click on hotlink in email text (URL)
2.
3.
1.In Firebird, click on hotlink in URL text (email address) 
Actual Results:  
In both cases, the helper app. will not open. Both cases give me the same
warning notice. Warning notice window is then hard to close. I must click the
close button repeatedly.

Expected Results:  
!. In Thunderbird, when I click on a hotlink (URL) in text it should open up
default helper app. Firebird window to that URL.
2. In Firebird, when I click on a hotlink (email address) it should open up my
default helper app. Thunderbird in a message window with the email address in
the "To:" field. 

This same problem happened in the old 0.6.1 milestone version of Firebird. When
I use Camino or Mozilla 1.5 as my default browser, it will open up the window of
the helper app (either the browser or email client) when I click on a hotlink,
so I assume the problem is in Firebird. Here is the warning notice that I get in
both cases:

Error launching browser window: TypeError:
Components.classes['@mozilla.org/appshell/component/browser/instance;']
has no properties
