Comment 16 for bug 240736

This is what I did to solve the problem. I am using Ubuntu 8.10 x64 with Compiz enabled. First, I un-maximized my screen, I noticed that the un-maximized window was beyond the dimensions of the screen and the tool bar (it fit in the screen but just barely), so I hit f11 twice and moved the window around by holding down alt and clicking on the fire fox window. Then I dragged the window down to a size that would for sure fit in-between the menu bars and fit on the screen. I re-maximized the window and quit firefox, now when I relaunch it relaunches in a standard window mode that is not maximized. I think the problem is that the application tries to snap the window within the screen resolution, it is possibly related to the window interaction with Compiz as well and this is just the way that Firefox deals with it. Try this and see if this helps :) Good Luck
