Comment 139 for bug 240242

Steps to reproduce this problem (In FF3):

1. Install Tab Mix Plus extension from
               http://tmp.garyr.net/forum/viewtopic.php?t=7031
2. Install the test extension above.
3. Tools->Tab Mix Plus Options -> Enable Single Window Mode.
4. In about:config, set javascript.options.showInConsole to true
5. Try opening new Firefox windows (not tabs), (You can do this via FF shortcut in windows) awesome bar stops responding.See Error console messages.

Fix for this problem is to add the handlers in the window only once.
Delicious Extension was incorrectly adding the handler twice. Please unzip the above xpi to see the code.

Thanks to http://tech.groups.yahoo.com/group/delicious-firefox-extension/message/3000 for reporting this scenario with Tab Mix Plus extension and delicious extension.

Warning: Use the above extension at your own risk, the standard disclaimers around backing up your data and unpredictable results all apply, Try it on a test setup profile only.
