If you search autofill in about:preference there's an option to edit saved addresses or are you looking to edit other information?

No there isn't. Does not exist in preferences. Do you need a screenshot? Or can you provide one of where it is for you? Please advise?

Oh weird, please send me a screenshot. This is what I see:

The address section doesn't exist here in the UK? Screenshot attached. I look forward to hearing from you and thank you in anticipation. Regards, Joanne.

Hi, please see if either of these articles help:

• Password Manager - Remember, delete and edit logins and passwords in Firefox.

• Control whether Firefox automatically fills in forms.

The Form Autofill feature is rolled out gradually starting with Firefox users in the US. Others can enable it by modifying some prefs via the about:config page. Close and restart Firefox after changing these prefs.

• extensions.formautofill.available = "on" (String)
• extensions.formautofill.creditCards.available = true (Boolean)
• extensions.formautofill.creditCards.enabled = true (Boolean)

You can open the about:config page via the location/address bar. You can accept the warning and click "I accept the risk!" to continue.

None of that helps?

I don't think that you can edit auto-fill data. You will have to remove (delete) existing data and save new data.

You can use these steps to remove saved items from an autocomplete drop-down list.

1. click the (empty) input field on the web page to open the drop-down list
2. highlight an entry in the drop-down list with cursor Down key
   do not click the mouse or press the Enter key
3. press Shift+Delete (68+) or Delete to delete the highlighted entry

Gosh. We do keep going round in circles. You have my screenshot. How can I edit details that don't exist in Firefox? I can't edit an address until one is added. There is no section to hold any address details as per the screenshot? Where in the screenshot, do you think I should be deleting, editing. Whatever. Please advise?

Do you have extensions.formautofill.addresses.enabled = true?
