I am surprised this hasn't been mentioned before. There is much simpler solution available that no longer requires add-on.

See this post for more details and screenshots:

Great, particularly with a Gmail account.

Sadly, it removes the indicator (along with the tooltip) showing the number of unread mails in the inbox, that normally appears when an account is fully collapsed.

This addon is fantastic with Google Inbox

Rated 4 out of 5 stars

Breakout/Promote both create Drafts/Sent/Junk/spam/Trash all moved out from being under Inbox, but all sub-folders I'd created were broken out of the Inbox too, below Drafts/Sent/Junk/spam/Trash.

It's kinda too simple options. It's either all or nothing. I couldn't find a way to breakout only Drafts/Sent/Junk/spam/Trash only, and leave my created sub-folders under Inbox.

Breakout loses your Inbox Folder from viewing. I haven't figured out if it shows up when new mail arrives.

Promote Keeps your Inbox, then lists Drafts/Sent/Junk/spam/Trash, then lists all your created folders. Not perfect, but acceptable.

Fixed the problem with IMAP folders all being under the INBOX. Almost perfect if the subfolders broken out were selectable!

I'd implore the developer to make the subfolders broken out selectable. Or, for another developer to improve on this cool little trick, which corrects the IMAP problem of all folders being under Inbox.

I discovery only today this litte jewel.
It is very useful for those who do not like the hierarchical structure folders in GMail under Thunderbird.
I presently use the latest TB version (45.1.0) and FlatFolderTree works perfectly!
You simply need to expand the .xpi file (which is exacly as a .zip file), open its .rdf file (which is a .txt file) with an editor (like notepad or notepad++) and change the label:
<em:maxVersion>3.1</em:maxVersion>
to, for example:
<em:maxVersion>50.*</em:maxVersion>
Being Italian I also added the translation for my language :-)

Worked perfectly for months, but isn't working anymore with Thunderbird/Icedove v.38.2.0.
Could you please fix it?
Thanks in advance :)

Excellent extension, but seems to be incompatible with the Hide Local Folders extension. Any possibility of rectifying that?

No sign of any extra view, and folder options are greyed out. NB, this is same with the 'compatibility solved' version DL and installed manually

shame, looked useful

This is very useful addon which enables Break out sub folders, Promote sub folders and Restore parent folder.

User NaTong claims this function is built into TB v17 but it does not appear to be anywhere.https://addons.mozilla.org/en-US/thunderbird/addon/flat-folder-tree/reviews/476672/It does still break any folder sorting done by "Manually Sort Folders 1.1", which is unfortunate that they don't work together.

These function can be set in v17.
No need these addon anymore.

This user has a previous review of this add-on.

Really useful extension, but, please make it play nicely with "Manually sort folders 1.1".

Rated 5 out of 5 stars

This extension is really a good job!
Now I want to reorder the subfolders list... I'm using another extension (Manually sort folders 1.1) which is very functional, but only when the subfolders are not promoted... when I promote, the order jumps back to the default used by Thunderbird.
Is there a way to resolve this?

Thanks

It's superb! But unfortunately I have the same problem as Ronald since I 've updated to Thunderbird v12. I have to unbreakout, breakout after every start to get it work. :( Would appreciate a patch! :) Keep up the good work! :) Cheers

Absolutely perfect! Good job!
Now my gmail looks nice in thunderbird

EDIT:
Could you please make a option to move folders up or down?
I would like to have my Junk folder from gmail over the archiv.
Example:

now:
&gt; Gmail
Inbox
Send
Trash
Archiv
Junk

I would like to have it like this:
&gt; Gmail
Inbox
Send
Junk
Archiv
Trash
