591011 - Double clicking on blank space on the tab bar resizes the window, rather than making a new tab when tabs-on-top is activated

Status: RESOLVED DUPLICATE of bug 575248

(Firefox :: Tabbed Browser, defect)

User-Agent:       Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0b4) Gecko/20100818 Firefox/4.0b4

Double clicking on the tab bar's blank space has always made a new tab. Now it's resizing a window.
There is a big distinction, although they are now combined, between the titlebar and the tabbar.

Double clicking in the titlebar should resize.
Double clicking in the tabbar should make a new tab.

Reproducible: Always

Steps to Reproduce:
1. Double click the tab bar, where there are no tabs (with tabs-on-top activated)
Actual Results:  
The windows resizes.

Expected Results:  
A new tab is made.

The Opera Browser does the Expected Results, so it's definitely possible.

This way, both functionality is possible.
