Firefox doesn't save web form entries

Firefox Firefox Last updated: 11/28/2018 33% of users voted this helpful

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.

Autocomplete does not work on certain forms

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.

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:

  1. In the Menu bar at the top of the screen, click Firefox and then select Preferences or Settings, depending on your macOS version.Click the menu button Fx89menuButton and select Settings.
  2. Select the Privacy & Security panel and go to the History section.
  3. In the drop-down menu next to Firefox will choose Use custom settings for history.
  4. Make sure that Remember search and form history is selected.
    • Enabling form autocomplete also makes Firefox store search history for the Search bar.
  5. Find Clear history when Firefox closes. If it is selected:
    1. Click on the Settings... button.
    2. Make sure that Form & Search History is not selected.
    3. Click OK.
  6. Close the Settings page. Any changes you've made will automatically be saved.

If either of those options were not set properly, setting them as above should enable form autocomplete.

Check for conflicting extensions

If you find that Firefox's settings were correct, but autocomplete still doesn't work on any forms, a Firefox extension may be causing the problem. See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems for how to troubleshoot extension issues.

If a conflicting extension was present, form autocomplete should work again after disabling it and starting Firefox again.

Check other programs' settings

Some Internet security software (including antivirus, antispyware, firewall, and privacy programs) will clear Firefox's form history. Check the settings for these programs if you have one or more of them.
