Display Quota extension will show you the current status of your IMAP quota in the statusbar and will warn you when you reach a configurable limit.
Note: It will only work if your mail server has an IMAP quota set: right click on your inbox, then in the "quota" tab of the properties, if a quota appears, you`re good.
Requirements:
· Thunderbird 1.5 to 5.*
