After entering and exiting fullscreen mode, new windows are created at "maximized" size (I use scare-quotes because OS X doesn't have a native notion of maximized windows) rather than at the size of the un-fullscreened window. Normally, windows are created at the same size as the most recently-created window.

Reproducible: Always

Steps to Reproduce:
1. Open a new browser window.
2. Enter fullscreen mode.
3. Exit fullscreen mode. The window should return to its original size (assuming it wasn't maximized to begin with).
4. Open a new browser window.
Actual Results:  
The new window opened in step 4 will be sized to fill the entire screen.

Expected Results:  
The new window opened in step 4 should be sized to match the un-fullscreened window.

This problem occurs whether the window in reproduction step 4 is opened immediately or it is created by exiting and re-launching the browser entirely. If the window opened in reproduction step 4 is resized, new windows opened after that time will be created at the same size as the resized window (as opposed to "maximized" size).

I haven't had an opportunity to try to replicate this behavior on other platforms yet. This bug may be related to bug 425086, but 425086 is seemingly Windows-specific. I don't think it's related to bug 454348.

I'm able to reproduce the problem Mac, but not on Linux nor Windows 7, using the latest nightlies.

The patch in bug 538242 fixes this.
