Description

[Michael Christensen]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4

After enabling browser.tabs.showSingleWindowModePrefs, closing a window opened
using window.open from javascript will crash the browser if the opened window
contains the following attribute in its BODY-tag:

onunload="window.close();"


Reproducible: Always

Steps to Reproduce:
1. Enable browser.tabs.showSingleWindowModePrefs in about:config
2. In Tools/Options/Advanced, enable "Force links that open new windows to open in:"
3. Select the "a new tab"-radiobutton
4. Press OK to close Options
5. Navigate to http://landscentret.lctest.dk/mac/crashbug/parent.htm
6. Click the button "Clicking this button will open a window, which will crash
Firefox when closed"
7. http://landscentret.lctest.dk/mac/crashbug/child.htm will open in a new tab
8. Close the new tab
Actual Results:  
The browser crashed

Expected Results:  
Not crash :-)

I have reproduced this on
- Debian GNU/Linux system with Firefox 1.03 (no extensions)
- Windows XP with Firefox 1.01 (some extensions)
- Windows XP with Firefox 1.04 (some extensions)
- Windows Server 2003 with Firefox 1.04 (no extensions)
