Much simpler solution - no add-on required Rated 5 out of 5 stars
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, but has one annoying issue Rated 4 out of 5 stars
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.
Works great with google inbox Rated 5 out of 5 stars
This addon is fantastic with Google Inbox
Worked in 45.5.1 using Topolo's fix below 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.
Very useful Rated 5 out of 5 stars
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:
to, for example:
Being Italian I also added the translation for my language :-)

Thanks in advance :)

Excellent extension, but seems to be incompatible with the Hide Local Folders extension. Any possibility of rectifying that?
Works as expected Rated 5 out of 5 stars

Great Add-On but it doesn't work anymore with Thunderbird 24.3.0.
Mostly good and still needed Rated 4 out of 5 stars
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. Rated 1 out of 5 stars
These function can be set in v17.
No need these addon anymore.
Nice Rated 4 out of 5 stars
Really useful extension, but, please make it play nicely with "Manually sort folders 1.1".
Ordering folders 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?
Superb Rated 5 out of 5 stars
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
