Hi duffer48, Firefox has a very powerful Password Manager. You can access it by going to ''Tools > Options > Security''. If you want to disable the feature completely, you can just uncheck the box next to ''Remember Passwords for Sites''. If you just want to remove your stored login information for a few particular sites, you can click on ''Saved Passwords'' and delete the entries for any sites you don't want stored. You should take a look at [https://support.mozilla.com/en-US/kb/make-firefox-remember-usernames-and-passwords this Knowledge Base article]. It has a lot of information on using and managing passwords. Hopefully this helps!
