How to Manage Firefox Autofill Settings

Enable, disable, and customize autofill on Firefox

Firefox autofill saves contact information, including physical addresses, phone numbers, and email addresses in the browser. It also collects information you input into online forms, all of which saves a lot of typing. Plus, you don’t have to memorize contact information for friends and family in addition to your own. Here’s how to enable and disable these autofill features and how to customize settings for autofill on Firefox.

You can also save login information using the Firefox password manager.

How to Use Form Fill in Firefox

In addition to addresses, Firefox can also save data you type into online forms. This feature is on by default. When the feature is on, if you type the first few letters of an entry into a form field, Firefox will show a drop-down menu with a list of saved items. Options include your name, email address, zip code, etc.

Click the down arrow on a blank field to see all the options. Use the down arrow to select the one you want to use and press enter or click it to confirm.

How to Delete Autofill Entries

You can delete any of the form data Firefox has saved if it’s incorrect or out of date, but you can’t do that in Firefox settings. You can only delete individual entries by using an online form.

  1. Click the down arrow in a form field.

  2. Select the entry you want to delete.

  3. Click Delete.

  4. Repeat this process for any other data you want to delete.
