Still a great add-on for version 24, just need a very small fix.
In the file "folderAccount_compose.xul" found within the .xpi file under "chrome/content", replace the string gAccountManager with the string MailServices.accounts and all is fine again.
This is a must extension for anyone managing accounts with multiple identities sorted to different folders.
