You could use Firefox Private browsing to not save anything (cookies, session data, etc). (CTRL + SHIFT + P)
Oh, sorry. Didn't think it was what you wanted so I edited it out of my original statement. Alright, autocomplete. In the sourcecode, you provide it as 'off' in an input tag. Demo: <input type="text" value="" name="username" autocomplete="off" /> Code (markup): This will prevent the browser from trying to autofill the username. Hope it helps.
