How do I set and save the default window size in Win 7?

The default size of my Firefox windows is too wide and too short. I can resize them individually by dragging their boundaries, but when I restart Firefox they return to that same annoying too wide and too short default size.

Used to be when I restarted Firefox, the browser windows would remain at their previous sizes, right where I had previously set them. It's aggravating to have to repeatedly resize my Firefox windows. My personal choice usually mimics the size of a "Portrait" page in my word processor, Often I want to see two windows side by side. I am about ready to go back to Internet Explorer, where I do not have to put up with this each time I restart IE,

What version did you have before this started happening? And what's the current version.
