In Firefox, to send an email, you click on the NEW EMAIL button in the tool bar and the email app appears. When you click on the TO button to add email addresses, the ADD RECIPIENT page appears and a list of people and their email addresses normally appear. THERE IS NO LIST OF PEOPLE AND EMAIL ADDRESSES. They have been moved to the PEOPLE folder on the left side tool bar below the top MAIL icon. The email list in the PEOPLE folder is still in tact My question is how do I correct this error which appears to have happened during an update. One would think if you highlight/select the PEOPLE email list it could be moved back to the ADD RECIPIENT list/folder but that does not appear to be possible. What is the solution????????
