Form fill won't fill only certain email address

I am using Yahoo mail. We had to delete on email address from the passwords list due to a password change. Since deleting it, Firefox's form fill will work with all of my email addresses except for the one whose original password was deleted.

Chosen solution

If the problem is with saving a new name and password for Yahoo the check this:

The Yahoo website uses autocomplete=off to prevent Firefox from saving form data like name and password.

You can remove autocomplete=off with a bookmarklet to make Firefox store form data like names and passwords.

Note that Firefox won't auto-fill saved form data automatically when autocomplete=off is used, so you need to double-click the empty name field to get a drop-down list.


Alternatively you can right-click the name input field and open the built-in Inspector via Inspect Element.
You can see if there is an autocomplete=off attribute and click the "off" text to edit this value and change it "off" to "on", so you get autocomplete="on".
Repeat this for the password input field, so both fields have an autocomplete="on" attribute.

Do you see any lines with an empty name or password field in the Password Manager?

  • Tools > Options > Security: Passwords: "Saved Passwords" > "Show Passwords"

Otherwise you may have to check the signons.sqlite file in the SQLite Manager extension to see if you notice entries that look corrupt.

thanks for your reply. I have no empty names or password fields in the Password Manager (with respect to login.yahoo.com).

I downloaded the SQLite Manager, but have no idea what I am looking at/for.
