Displays your IMAP quota in statusbar
This extension will display the current status of your IMAP quota in thunderbird’s statusbar and will warn you when you reach a configurable limit.
It only works with IMAP quotas and servers advertizing the quota status via IMAP the IMAP GETQUOTA command. Some mail servers have disk quotas and will send email when your mailbox reach its quota. That’s not a real IMAP quota system and the imap server might not advertize it.
