Comment 62 for bug 885525

FYI.
A way to access [Gmail]/Trash from Thunderbird again to copy/move mails to [Gmail]/Trash, after unsubscribing [Gmail]/Trash in order to use "other than [Gmail/Trash" as trash of "move to trash" model.
(A) Change to "Just mark it as deleted", subscribe [Gmail]/Trash, copy/move mails to [Gmail]/Trash, unsubscribe [Gmail]/Trash, go back to "Move to trash" model.
(B) Create two same Gmail IMAP accounts in a Tb with different server name,
 (i) with hostname/realhostname = imap.googlemail.com (auto-config only)
 (ii) with hostname/realhostname = imap.gmail.com (auto-config with Manual Setup)
and set different options.
 (i) As you want for your daily use, with "Show subcribed folders only"
 (ii) All folder is Offline-use=Off, Just mark it as deleted,
      disable "Show subscrbed folders only", disable IDLE comand use,
      max cached connections=1, disable automatic new mail check, ...
