Mozilla question

I recently got mozilla instead of that nOOb IE thing I'd been using. Anyway it has a funtion that remembers your login and password on sites for you. On one of the sites where I wanted it to do this for me when it asked me if I wanted it to remember the login info I accidently clicked "never for this site" so now how do I get it so I can get that to come back up again so I can tell it to remember it for me instead?

I'm running Firefox, so it may be a bit different, but in Firefox it's Tools>Options>Privacy>Saved Passwords, then go to View Saved Passwords, and then click on the "Never Saved" tab, then remove whatever site you want to save your password.
