Hi
I am using Firefox 4.0 Beta 1
I did search the bug list but could not find this reported.
It is a minor issue still thought of posting the same.
Please follow the steps described below

Reproducible: Always

Steps to Reproduce:
1. Open firefox 4.0 Beta 1
2. Make the browser maximized using the maximize button
3. Now Press the F11 ( Full screen) Button
4. Once the window becomes full screen press "Esc" Button
Actual Results:  
The window should return to the maximized position from where it was made full screen

Expected Results:  
The window becomes re-sized automatically and pops up the inital window which is not acceptable 

Happens all the time
