How do I fix the display size Firefox is using?

Whenever I open Firefox now, the display fills up my whole screen, covering everything, regardless of what size it was when I last closed it. I want it to be smaller so I can see other things on my desk top, and now I have to manually change the display size and center it on my screen every time I open Firefox. How do I set it so it will use the same display size it was the last time I closed it? Thanks.

Try to remove the Firefox plist file (org.mozilla.firefox.plist).

Go to "~/Library/Preferences" and remove the plist file for Firefox (org.mozilla.firefox.plist)

Thank you very much, FredMcD. That seems to have done the trick. I also want to thank cor-el for his/her response, although it appears (so far) that I didn't need to try it. This is the first time I've submitted a question, and I'm both impressed and grateful for the rapid response and for the help. Thanks again and keep up the good work.
