Firefox back button erasing text?

I am using Firefox 4.0.1 running on Windows 7x64.

Whenever I'm on a webpage and click the submit button and then need to go back (using the back button), any text I had typed always gets cleared. Is there an option with Firefox to have it remember what was typed? I sometimes do a control-C to copy stuff so I can repaste it. But it seems like whenever I forget to and have a lot of stuff typed is when the subsequent page gets an error and I need to go back (e.g. long answers typed on Y!A seems to trigger it a bunch).

There is a way, since mine does it automatically. Try going to the options and looking around.
