All windows, and even when I drag the corner to maximum size it doesn't "save".
My two biggest annoyances are FF and Seamonkey Composer.
Right click on the top border, after you have the window set to the size you desire.
Choose Advanced --> Special Window Settings. In the new window that pops up, check the box for the first item,
Position, then from the drop down menu
Remember. Do the same for the second item,
Size. If you want the window to always open on the same desktop, also do the same for the sixth item,
Desktop. There is another drop down menu where you can
select the specific desktop if it differs from the one currently on.
There are nine items for which you have choices. Use the ones that apply to your needs. When you are done, click the
OK button at the bottom right.
