I want to disable firefox' form history so I don't see the drop-down menu for email addresses I could enter into forms. However, I do not want to disable search history. In the settings, I only have the option to enable or disable both (see the attached screenshot). I would appreciate it if search and form history could be disabled or enabled separately. The reason this is important to me is that when logging into websites, I often use [personal handle]+[website]@[email provider] as my email address so I can avoid spam if that site's data gets leaked. However, firefox' form history stores each +[website] as a separate entry, resulting in an impractically long drop-down menu. While it doesn't break anything, it does mean choosing between not using search history or having my screen fill up with a large, useless, attention grabbing drop-down element every time I have to log in.
