Firefox can remember what you've entered in forms on web pages, also known as text fields. After you've entered something into a form on a web page (such as a search box), the next time you visit that page, your previous entry should be available to re-use. If you find that you can't re-use your form entries, follow the instructions in this article.

• For more information on the form autocompletion feature, see the Control whether Firefox automatically fills in forms with your information article.

Autocomplete does not work on certain forms

Deliberate prevention from web sites editors

If you find that Firefox will save form entries for forms on only some websites, but not on others, the site might be telling Firefox to not save form history. This is especially common on email and banking websites.

Technical details: This is typically achieved by the web sites editors by using form entries of the form <input autocomplete="off"/>.

Form entries change over time

There is also another seldom seen possibility causing a form entry not to be remembered: a specific form entry might have been a password input in the past and then the web site editors changed it later on to be a plain text input. Thus Firefox may have stored the form entry as a password, typically with an empty user name. The solution to have the form entry to be remembered is to go to the Password Manager and to delete the remembered password which is erroneously associated with this form entry.

Autocomplete doesn't work on any forms

If you find that Firefox will not save any text you enter into forms, follow the instructions below.

Check Firefox settings

Make sure that Firefox is set to remember form entries and that saved form entries are not being automatically cleared:
