Is it ok that autocomplete shows options when using a private windows?

Private windows should leave no record of previous usage in the computer, right? When using a private windows, autocomplete is offering options, and moreover options of fills I have never used. For example, when trying to login to an email account, I get the options for accounts that are not mine (nor of any friend that has ever used my computer).

Is this ok (if so, why? shouldn't there be no info stored at all) or should I be worrying about my computer/network being compromised??

Private Browsing stops any records from being saved.

Auto complete is a separate function.

Ok, but how do this two interact? In my normal tabs auto complete gives me options I have used before myself. Should I be worrying that in private mode it is giving me options I have never used?

Private Browsing - Use Firefox without saving history Firefox Private Browsing is great for viewing websites without saving things like cookies, temp files, and a history of the pages you visit. https://support.mozilla.org/en-US/kb/private-browsing-use-firefox-without-history

Saved form data isn't bound to a specific domain AFAIK, but is stored under the name of the field, so you might possibly see autocomplete data saved elsewhere if the same name is used.
