Available on Thunderbird 38.1.0 Rated 5 out of 5 stars

In Thunderbird 38.1.0, Folder Pane Columns is a built-in feature.
If you run with the traditional menu bar (selections at the very top of the window), the option is View | Layout | Folder Pane Columns .
If you use the application menu (an icon of three horizontal lines near the upper right of the window), the option is Options | Layout | Folder Pane Columns .
In some localizations, it might be Preferences | Layout | Folder Pane Columns .
But note that under the application menu, the Layout option is *not* under View.

No longer working Rated 5 out of 5 stars

I loved this addon, been using it for several years but since updating Thunderbird to version 38.1.0, this addon has been disabled because it's not compatible with that version. Will there be a new version soon? One that works with the latest version of Thunderbird?

Yes -- it does work. Rated 5 out of 5 stars

There is no "Options" menu. The way to get the extra column to appear is using the View menu .. View...Layout .. and then check Folder Pane Columns. And thanks to those who noted this issue.

Yes, built-in now! Rated 5 out of 5 stars

Yes, Extra Folder Columns is built in now, but in order to enable it you must modify with config editor the key

mail.folderpane.showColumns and set to true

ARB suggests to go to Options -> Layout -> click Folder Pane Columns but the option does not exist.

ARB and Unknownhtml said that tb 38.0.1 has Extra Folder Columns built in.
Great, but I can't find it in mine Dutch version.
Not under options and not under view, if mine translation is correct.

Built-in now -- corrected directions for use Rated 5 out of 5 stars

It's nice that it's built in now (although maybe I preferred the add-in's layout? Just me..). Here's how to enable it:

Options -> Layout -> click Folder Pane Columns

Then you can customize it at will.

upgrade for Thunderbird 38.0.1 please

No longer needed for 38.X -its built in under View -Layout - Folder Pane Columns Rated 5 out of 5 stars

I have used this since it was first published and will miss it but this functionality is now built into v38.x.

Go to View - layout - Folder Pane Columns and select -

Exactly like this add-on now just built back in...finally!!!

You will need to enable the MENU bar to see VIEW and select from there if you are using windows. I haven't checked out Mac options yet but will test on VM and report back later.

You do NOT need to enter any config editor option to enable.

I miss this functionality. Let me add my vote - please hurry and update this add-on so I can use it with Thunderbird 38.x

Extra Folder Columns Rated 5 out of 5 stars

Extra Folder Columns is such a great feature. PLEASE create a version compatible with 38.x!

Solution needed for 38.x (embedded function differs)! Rated 5 out of 5 stars

The following is not true -- there is a config setting called "mail.folderpane.sumSubfolders" which defaults to "true", when set to false it gives exactly what EFC gave me before, perfect!

This was my previous report, it's invalid now:
I hope the author will make an update (or adjusts the version) so the add-on can be installed on Thunderbird 38.1 -- I know that you can add folder columns natively in TB now but here you can only choose the "number of unread messages" or the "number of total messages" (including subfolders) -- but I need the number of "messages in the top level folders" (no matter if read or unread), my subfolders are all archives while the toplevel folders are "active". Thunderbird misses that value while EFC had it...

Incompatibility with thunderbird 38.0.1 Rated 5 out of 5 stars

Very nice tool. Unfortunately last comatibility with 35.x.x thunderbird. Is it in plan write new version for 38.0.1 ?
I know, mozilla (and firefox) team make big mistake, followin hurry uping with numbering revisions. Why internal interfaces aren't versioned? addons are (in)compatible with internal interfaces, not with all thunderbird.
Why numbering doesn't follow major/minor versioning?
first number, copletly new version what optionally follows compatibility with specified previos version,subversion. second number, it is some minor improvements, with all backward compatibilities with this major version. second subversion is only ad-hoc security/stability fixes. Why it is NOT supported by mozilla similar to old supporting school ?

Thank you Joey Minta for one of the best add-ons to Thunderbird!

I used it religiously and had it installed on 100s of my clients/friends [for I can't remember how many versions of Thunderbird but at least 15 releases] as a way to get them to curb and be aware of their mounting emails!

Anytime you're thinking of making a new Add-On - give me a shout and i'll beta test it!



Thank you! After TB38 this plugin is not needed anymore. Rated 5 out of 5 stars

Thanks for this plugin. As of TB38 this is incorporated into main functionality again, which was missing since TB2. It took many years to do that.

v38.0.1 Rated 5 out of 5 stars

Will it ever be adjusted for Thunderbird v38.0.1?

Nevermind, I just checked for the fix:

Set check mark on "View/Layout/Folder Pane Columns" and normal operation will return.

Как сделать, чтобы дополнение заработало Rated 5 out of 5 stars

Устанавливать это дополнение в Thunderbird 38+ уже не требуется, оно встроено в программу. А для того, чтобы заработало, нужно зайти в меню Вид - Разбивка окна и установить галочку на "Колонки панели папок". Вуаля! :)

No need anymore now builtin TB 38 Rated 5 out of 5 stars

Thank to built in TB 38.
Bye~ bye.

Now built in to TB 38+ Rated 3 out of 5 stars

I loved this addon and have used it for years, but if I'm not mistaken it's function has been incorporated into TB itself in TB 38+. To activate columns, just open the little square icon with an arrow at the top right of the Folder Pane. No more 4KB issue either. I don't think there is a reason to keep this addon installed.
