Status: RESOLVED WORKSFORME

(Firefox :: General, defect)

Description

[Andrew Benton]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7a) Gecko/20031231 Firebird/0.7+ (persist,gtk2+xft)
Build Identifier: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7a) Gecko/20031231 Firebird/0.7+ (persist,gtk2+xft)

If Thunderbird is running I can't open Firebird. I get an error

Error launching browserwindow:TypeError:
Components.classes['@mozilla.org/appshell/components/browser/instance;1'] has no
properties

This used to work for me. This build I made on the 31st of Dec launches fine but
if Thunderbird is running, my build from the 2nd of Jan (and all builds since)
fail with the above error


Reproducible: Always

Steps to Reproduce:
1.Open Thunderbird
2.Launch Firebird
3.

Actual Results:  
Error launching browserwindow:TypeError:
Components.classes['@mozilla.org/appshell/components/browser/instance;1'] has no
properties


Expected Results:  
Firebird should open

I'd say that this has to do with Thunderbird and not with Firefox, since it
happens with Mozilla as well. If Thunderbird is running, neither Firefox nor
Mozilla can be started (you can't even open a new window, though tabbed browsing
does not seem affected) and the mentioned error message is shown instead.

WFM.  Are you starting with run-mozilla.sh, or running the actual
thunderbird/firefox binaries?

Comment 3

[Robin Monks]

Reporter, can this be reproduced in newer versions of Mozilla Firefox?

No, I can't reproduce this now. This has been "works for me" for a while. Sorry,
I'd forgotten about this old bug.
