Control whether Firefox automatically fills in forms

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 will be available to re-use. This article describes how to use the auto form fill feature and how to clear or prevent it from storing form entries.

Using Auto Form Fill

To use your previous entry in a form:

  1. Type the first few letters of the entry into the form field. Firefox will display a drop-down menu with what you've typed into the form before.
    • You may see a list of all the entries stored for a particular form field by pressing the key when the field is empty.
  2. Press the key to select the entry you want to re-use. Press EnterReturn when the appropriate entry is highlighted. The text of the entry will appear in the form field. You may also use the mouse to click on the entry.

Deleting individual form entries

If you want to remove one of your previous form entries from Firefox's history:

  1. Click on the form field and press the key to display all the saved entries. You may type the first few letters of the entry to limit the number of entries displayed.
  2. Use the key or the mouse pointer to highlight the entry you wish to delete.
  3. Press Shift+Delete. The entry will be removed.

Repeat the process for each entry that you'd like to delete.

Clearing form history

If you want Firefox to forget all of your previous form entries:

  1. At the top of the Firefox window, click on the Firefox button, go over to the History menu and select Clear Recent History….On the menu bar, click on the History menu, and select Clear Recent History….At the top of the Firefox window, click on the History menu, and select Clear Recent History….
  2. In the Time Range to clear: drop-down, select Everything.
  3. Click the arrow next to Details to display the list of items that can be cleared.
  4. Make sure only Form & Search History is check marked.
  5. Click Clear Now. The dialog box will disappear and your form history will be erased.
  1. Click on the menu button New Fx Menu .
  2. Click History, and then Clear Recent History….
  3. In the Time Range to clear: drop-down, choose Everything.
  4. Click on the arrow next to Details to display the list of items that you can clear.
  5. Make sure Form & Search History has a check mark next to it.
  6. Click Clear Now to clear your form history and close the dialog box.

Prevent Firefox from storing form entries

If you don't want Firefox to remember what you've entered into form fields, you can turn off the auto form fill feature:

  1. Click the menu button New Fx Menu and choose Options.Preferences.
  2. Select the Privacy panel.
  3. In the drop-down menu next to Firefox will:, choose Use custom settings for history.
  4. Remove the check mark next to Remember search and form history.
  5. Close the aboutSmiley Tonguereferences page. Any changes you've made will automatically be saved.

Disabling form history also prevents Firefox from storing search history for the Search bar in the Navigation Toolbar.

Re: Control whether Firefox automatically fills in forms

"Control whether Firefox automatically fills in forms with your information" is 74 characters long, including spaces. This article's title comes up truncated in search results. For example:

Google search: Control whether Firefox automatically fills in forms with your ... Yahoo search: Control whether Firefox automatically fills in forms with ...

What about dropping "with your information" from the title and rename it to this? Control whether Firefox automatically fills in forms

Any other suggestions?

The original title of this article, by the way, was Form autocomplete (it was renamed as part of an IA project a few years ago).

I agree with dropping "with your information". I'll change it now.

Re: Control whether Firefox automatically fills in forms

For the release notes on version 38 there is a portion that is changed for both mobile and desktop that "autocomplete=off is no longer supported for username/password fields"

It might be worth mentioning this change here for questions about how users can turn on or off this feature. The only difference I see is wether or not the option to save passwords is on (maybe this should be added to another article instead like http://mzl.la/1BAQDYP or http://mzl.la/1xKrEoj)
