How do I Autofill email addresses in Firefox?

You can enable or disable the autofill feature for email addresses in Firefox through the settings. Here's how:

1. Open Firefox Settings: Click the menu button (three horizontal lines) in the top-right corner and select Settings.
2. Navigate to Privacy & Security: In the Settings menu, click on the Privacy & Security panel.
3. Scroll to Autofill: Scroll down until you find the Autofill section.
4. Enable or Disable Address Autofill:
   • To enable email address autofill, place a checkmark in the box next to Save and fill addresses.
   • To disable email address autofill, remove the checkmark from the box next to Save and fill addresses.

That's it! Firefox will now either save and suggest addresses based on your selection. Note that this setting controls autofill for all address fields, not just email addresses.
