I do not think this is normal operation, so I am unsure if this is Firefox's fault or the website's fault. I was just doing something on Paypal.com and when it came time to fill in my social security number, it had "suggestions" pop up under the fields with my SSN that it remembered before. Things like SS# and credit card numbers should not be remembered like this because it's a major security issue for if someone else uses my computer.
I do not want to disable remembering fields entirely because that feature is useful to me. Names, addresses, phone numbers, emails, is all okay to be auto-filled in, but not something as extremely sensitive as SS#'s.
Again, sorry if this is Paypal's fault. I will be contacting them instead if it is.
Thank you for any information you can provide.

Thank you for your response but you must have misunderstood my inquiry.
I am perfectly aware of how to clear my Firefox cache and cookies and also aware of what they are.
I fully understand the purpose of storing your addresses, names, email addresses, phone numbers, etc. What I do not understand is why Firefox stores social security numbers. This is a security flaw. I never got FF storing my credit card numbers, so why is it storing SS numbers?
Your solution is only a temporary fix. As soon as I next enter my SS number on a website, Firefox will store it again. I want to prevent this from happening.
Again, if Firefox is not able to discern SS numbers and it is the website's job of distinguishing them to not be stored by the browser, please tell me so that I can notify the website instead.
SSN's might get stored as part of form history and not recognized as such, depending upon how the Field Name of the on-page form is labeled. Clear your Form and Search History or don't save that data to begin with.
Or get in the habit of opening a New Private Window when confronted with the need to insert SSN's which might get saved in Form History.
Firefox has a built-in algorithm to check for credit card numbers (Luhn), but not for other privacy sensitive numbers.
Thanks for the insight, cor-el; just the kind of response I was looking for! Thanks everyone else for your responses also.
