Description

[Paul Wilson]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3

I browse to a webpage that resizes my window (smaller), lets call it the destination page. I then maximise that window. I use the 'back' key to return to the previous page that I'll call the originating page. The originating page is displayed in the same dimensions as the destination page was resized to, prior to maximizing. 

Reproducible: Always

Steps to Reproduce:
1. Load firefox 3.5.3 (homepage Google)
2. Enter shop.orange.co.uk/shop/terms into address bar and go.
3. See that firefox resizes smaller
4. Hit the maximize button on the window
5. Select to go back to the google homepage via 'Back' button.
6. See that firefox displays google homepage in reduced size surrounded by grey.
Actual Results:  
Small web canvas with large grey border

Expected Results:  
Web canvas fills the whole areas with minimal grey border.

Firefox 3.5.3 :

Mozilla/5.0 (Windows; U; Windows NT 5.1; en-GB; rv:1.9.1.3) Gecko/20090824 Firefox/3.5.3

I still see this using Firefox 4.

The orange.co.uk link doesn't try to resize the window anymore, but I see the same behavior on another site.  (It requires a login to get to the page, though, so I can't just provide a link.)
