Copy Sent to Current 1.2.3 Firefox 57 以上に対応
作者: Guenter Gersdorf
Allows to place a copy of sent messages (aka FCC) into the currently active folder or any other folder you choose, when you create the message. Usually the copies are placed into the 'Sent' folder. For replies, you may also move the original message.
Useful, if your mails are presorted e.g. on an IMAP-Server, and you want answers to a mail be saved along with the original mail.
Please NOTE: You have to activate the add-on for each account in the 'Account Settings' in the section 'Copies & Folders'. There is a new radio button 'select on send'.
For all people who would like to have another default folder, please consider changing your behavior: First select the desired folder in the folderpane, then create the new mail.
Please use latest version from the homepage (http://www.ggbs.de/extensions/CopySent2Current.html)
