303210 - Maximize only maximizes window to only about 5/6 of the screen width using Window -> Zoom or (+) button in title bar

Status: RESOLVED DUPLICATE of bug 232919

(Firefox :: Shell Integration, defect)

Description

[u211322]

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.7.10) Gecko/20050719 Firefox/1.0.6
Build Identifier: Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.7.10) Gecko/20050719 Firefox/1.0.6

I'd expect the (+) button in the title bar or the Window->Zoom menu entry to
resize the window to the full size of the screen as nearly every other
application does in MacOS X. Firefox resizes the window to about 5/6 of the
screen width.

If I then resize the window to use the full screen by using the handle in the
lower right corner of the browser window the behaviour of a fully zoomed window
is lost and I experience the problems found in this defect:
https://bugzilla.mozilla.org/show_bug.cgi?id=218214

Reproducible: Always

Steps to Reproduce:
1. close firefox
2. open firefox
3. click on the green (+) button in the title bar

Actual Results:  
the window was resized to the full height of the screen and about 5/6 of the
screen width.

Expected Results:  
the window resized to full height AND full width of the screen.

Reporter, you're originally a PC-user, right ? The green button on the Mac means
"zoom to optimal size", not "full screen". This normally means that the window
will use the height of the display (if the page is longer than the height). But
it doesn`t necessary mean that we`ll use the full width, we`ll also have to take
the aspect ratio in account. See the discusssion inbug 237404.

See also bug 232919 for a further refinement (we still don't do it correctly).
I`ve duped it against that one, because bug 237404 is already closed.
