Do you mean names and passwords in the Password Manager or do you mean that you are no longer logged on to (remembered by) websites after closing and restarting Firefox?

There is a difference between remembering the name and password in the Password Manager and a "remember me" check box on a web page to log you in automatically. The latter usually involves the creation of a special "remember me" cookie that is stored on your computer and that is send to the server. If this "remember me" cookie is removed or gets corrupted or is not send to the server then the server won't remember you and you will have to sign in once again. You can remove this "remember me" cookie to make the website forget you and require you to sign in again.

• Create a cookie 'allow' exception to keep such cookies, especially in case of secure websites and when cookies expire when Firefox is closed.
• Tools > Options > Privacy > "Use custom settings for history" > Cookies: Exceptions

DO I REALLY HAVE TO SPELL IT OUT FOR YOU?!?!?!?!?

I did NOT say "active logins" I SAID PASSWORDS!!! and I SAID there is NO autocomplete and I SAID it asks if I want to save (remember) the password after I log in despite I SHOULD HAVE ALREADY HAVE IT SAVED!!! are you seriously that dumb that you CANNOT understand my problem from my description??? are you like 8 years old???

There is always a lot of confusion about passwords and websites remembering you (i.e. you tick a box on the login page), so I always ask for confirmation. If Firefox has saved the name and password in the Password Manager and you still see it there then it is possible that the server uses multiple domains. You might not notice this if this is about the URL that the form is submitted to. It is also possible that there is a script running on a web page that modifies the form fields if it happens all the time on a specific website.
