When I receive or send Emails, every time an email address comes up it is usually shown in blue or another colour in the text and if you run your cursor over the email address it can be copied and placed where ever you need it either in another email or into the address book which is what I was used to in my Email account with another Server however, when I try to click and copy to paste it this function is not available in your version of copying or sending Email addresses? For example when I send my Email address thus: < [email protected] > you cannot copy it to send anywhere else or put same into my Email Address Book List???? Please tell me if this is available to do on Thunderbird or not? I Remain, Yours Faithfully, RONALD H. MAY, NEW EMAIL CLIENT. DATED: 28/06/2017
