Strange accounts in auto complete history of saved account fields
like in [https://support.mozilla.org/en-US/que.../1358775|this] this article. I see stranger accounts in my browser saved session suggestions. I only use my ff account in my personal computers and i'm not share my computer with strangers & guests. (this does not mean no one used after i leaved a computer with resetting that computer). Rarely using my personal computer(s) in public networks.
Do you have any ideas why this is happening and how can i prevent ?
