I found it convenient that folders that I don’t use as often ( Sent Mail, All Mail, Spam) can be collapsed, reducing vertical height of the account in the folder pane. AfterwordĪfter using it for a while I ended up not using the solution above to hide folder. The workaround is to add / in front of the label’s name. With this solution you will not be able to see your custom folders (labels) anymore. In the Advanced Account Settings window change IMAP server directory to and click OK.Īfter restarting Thunderbird all folders are shown in a single-level list. In the Account Settings window select Server Settings and click the Advanced button. Right click on the account in the folder pane and select Settings.

I am surprised this is not mentioned in the official guide. However the solution I discovered is much simpler and does not require any add-ons. I have started using gmail thru Thunderbird and every incoming email is duplicated 3 times (it will appear once in the Inbox folder, once in the Gmail/All Mail folder and once in the Gmail/Important folder).

Mozilla recommends using Flat Folder Tree add-on to show all the sub-folders of the IMAP’s folder at the same level than your other folders. Mozilla has published Thunderbird and Gmail set-up guide which shows the same folder on screenshots. This is how my account was shown after I configured Mozilla Thunderbird for Gmail using IMAP protocol.
