Status: RESOLVED DUPLICATE of bug 479291

(Firefox :: General, defect)

Description

[John Fitzgerald]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3 (.NET CLR 3.5.30729)
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3 (.NET CLR 3.5.30729)

If you have two windows open, if you try to navigate to a non-existent domain in the first window, the second window will improperly try to load a new page which results in an error.

Reproducible: Always

Steps to Reproduce:
1. Open Firefox
2. File -> New Window
3. In FIRST window, type www.anynonresolvingdomain.com in the address bar and hit Enter
Actual Results:  
The title bar of the SECOND window says "Problem loading page" and displays the error:

"File not found" error
Firefox can't find the file at jar:file:///C:/Program Files (x86)/Mozilla Firefox/chrome/en-US.jar!/locale/browser-region/region.propertieswww.anynonresolvingdomain.com.

Expected Results:  
My second window to remain on the page it was at before I tried to browse to a non-existent domain in my first window.

This only happens with the first new window you open, not the second, third, fourth, etc.
