I seem to be unable to delete an unwanted contact from the list of offerings in "To:" section when starting an eMail. (I have tried others with same result.)
"Help" section says I should highlight the unwanted, then click to "X" on right of name.
I do this, Yahoo Mail responds "Succesful Permanent Deletion", but the contact remains and is offered again in next email attempt.
I use Currently Update Firefox. I have "deleted history" (Cleared Cache).
Guidance please ?
