442817 - An XmlLayer Window that appears when I run Firefox

Status: RESOLVED INCOMPLETE

Description

[Steven]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9) Gecko/2008052906 Firefox/3.0
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9) Gecko/2008052906 Firefox/3.0

When I open my Firefox 3, I notice that by pressing Alt+Tab, I see an invisible window called XmlLayer. Also, the only way to close it is to press Alt+F4 while I'm in it, from using that Alt+Tab menu. This window is irritating because it interferes in my using multiple programs at once. I like using Alt+Tab to quickly go back and forth between windows that I have open, plus I don't even know what the reason for there being this extra window just from opening Firefox. It also appears in the Task Manager.

Reproducible: Always

Steps to Reproduce:
1.Open Firefox
2.Put in Master Password (not sure if that matters) and that's all it takes
Actual Results:  
Like I said in the Details, I have an extra, invisible window called XmlLayer, that I can find by either going to the Alt+Tab menu or opening the Task Manager.

Expected Results:  
Well, I've only had this happen before once. Before that, only the main Firefox window appeared, none else.

I can not reproduce this problem with FF3.0 on vista (but without master password).

Do you get the same problem with the firefox safemode ?
