This add-on is one of the best things about Thunderbird. I've never used the categories feature, but decided I'd give it a try today. But when I try to add a new category, it just won't take. Everything else works perfectly. Categories would make this add-on even better, so I hope the next update will have that ironed out?

This review is for a previous version of the add-on (4.15.1).  This user has a previous review of this add-on.

thanks for the review! I use QF categories all the time - best thing if you can get in touch via the "support" tab on the QuickFolders Options screen - there is a link to send me a direct email on the bottom!

This is an incredibly useful add-on. If you use Thunderbird professionally and have a well structured directory/subdirectory organization for your thousands of emails, you need a way to get to the 3 or 4 main directories that you access most frequently. This Add-on provides that functionality. I tested it for 5 minutes and gave them the $15 fee for Pro version as a donation. To the creators of QuickFolders--- great add-on, thanks for doing this work.

Thanks - if you are looking into future proofing for next years version of Thunderbird (ESR 68, due to come out after July) you can check out my conversion efforts (and download trials) here:
https://www.mozdev.org/bugs/show_bug.cgi?id=26658

Note that b/c of technical reasons, the new version is not compatible with the current Thunderbird version (60) - functionality will be the same, as much as possible and pending on any future restrictions coming down the pipeline from Mozilla.

This is super. Thank you so much, it's so useful and means I can check far more quickly than opening each e-mail client. Well done.

This is really a very useful addon. Unfortunately, it does not work anymore with Thunderbird 57.0b1. I had to start Thunderbird in safe-mode and deactivate it.

It's complicated but there are some explanations and a working test version available there.

Incredible how easy sorting and archiving is with this tool. It safes time and nerves - especially if main working area is connected to emails and you receive a jungle of emails to sort through everyday - and I'm not talking of Spam! I bought the Pro and it's worth every cent!

One of the best addon to have in Thunderbird !

I've searched for years how to improve Thunderbird and his awkward tabs functionality. I found nothing, and had to deal with the left sidepanel and my twelve accounts spaming litteraly my screen.

just today, I came here (again for the thousandth time) to take a look at something new, and... oh god ! I found the graal.

This is just what I always wanted for. It's perfect. there is tons of options, it's a TRUE extension made by professionals.

I managed to simplify Thunderbird like if it was a totally new program, by cleaning the general toolbar and moving it near the menu bar, unchecking the "Mail toolbar" to let the Quickfolder toolbar display correctly, and hidding the left sidepanel. And I even managed to shorten the Quickfolder toolbar by unchecking some stuffs in the options, letting me stack many tabs for all my accounts without reaching the right side of my screen.

Sincerely, it's an amazing work. I'm stunned. BRAVO ! And THANK YOU !

.. if you care about your _main_ menu styling also check out my "menu on top" addon. It also has some mini bookmark option so you can actually add important emails / tabs (just like the QuickFolders reading list, but that one does only do emails)

I've been using this add-on for several years now and find it extremely useful for keeping my email organized. I'm a heavy user of filters, folders, and sub-folders and having color coded tabs for my most used groups of email is essential. And it keeps working consistently, release after release.

I missed this so much, I reverted to TB45

This review is for a previous version of the add-on (4.5). 

... there is already a bug fixed beta version here:

I recommend waiting for the official release of QuickFolders 4.6 - we are just in the process of moving the web site, and will release once that's complete!

Really like QuickFolders. Hugely improves Postbox functionality.

Some issues with Postbox 5 but instant response from the developer and new beta version works fine.

No problems with Pro license, works perfectly, though not too keen on subscription model for license

QuickFolders Free & Pro rate PLUS 5-Stars!

The only major shortcoming of Thunderbird and PostBox is the inability to easily organize and manage a large collection of folders. That's where QuickFolders comes into play.

QuickFolders offers a easy, quick, and sensible way to organize and manage folders. It is a lightweight, unobtrusive, and stable extension. Also, it comes with other several useful features. Additionally, the Developer quickly answers all support requests and goes the extra distance to deliver great customer service.

The FREE version is adequate. But the extra features in the Pro version are well worth the small cost of $15. Plus, that $15 helps to keep the developer in business and updating QuickFolders. I urge all to buy the Pro version.

THERE IS ONE SMALL CATCH WITH THE PRO VERSION'S LICENSE for those who use multiple email clients on the same PC...but there is an easy fix. I will explain.

The Pro license is 'assigned' to one specific email address...which is the email used when purchasing the license. That licensing method can cause an issue when using multiple email clients. Here's how.

The QuickFolders extension works in both Thunderbird and PostBox. (Postbox is Thunderbird optimized for Gmail.) BUT the Pro License will register to only one of the two email clients. Thus, a second Pro license is required to get Pro to work in both email clients.

(I use Thunderbird strictly for my Microsoft email accounts. Then I use PostBox for my gmail accounts.)

I BOUGHT THE PRO LICENSE UNDER MY GMAIL ADDRESS. Therefore, I can only use the Pro License in an email client 'hosting' that gmail address, which is PostBox. CONSEQUENTLY, I can NOT use the Pro License in Thunderbird (because I don't do gmail in Thunderbird).

The Pro Licensing System requires buying multiple Pro licenses when using different email clients installed on the SAME PC. But there is an easy fix.

If you find yourself in the predicament described above, email the developer Axel Grude and tell him. Then the Developer will fix things so that the purchase of one Pro license will register QuickFolders Pro in all email clients on the same PC.

Phew-w-w!

"BUT the Pro License will register to only one of the two email clients"

you're misinformed. The pro license is registered to one specific email address, but this can absolutely be used on multiple / different Thunderbird / Postbox / SeaMonkey installations, both on the same and separate machines. The email address is the key, not the number of installations. If you think you experience something else, I will need to debug the problem because as I describe is the way I have designed it. I will not rule out that you may have found a bug although I doubt it at this stage.

you can used it on many installations, you just need one common email address to verify your license, but you can have 10 or more additional email addresses.

If you want to use 2 different mail addresses on 2 separate accounts (and not share the same key), then please get in touch and I can give you a free license for your second use. I just need to know the second address.

It is just technically very difficult to "spy" different installations on the same system (on 3 different operating systems, Windows/Linux/Apple this would be several weeks of work and may prove unreliable) and email addresses are much easier to verify as unique. I have no problem in providing a second free license, just get in touch instead of doing a review because I cannot help you that way. There is a link on the options dialog to get in touch.

I am still working with the customer to resolve this situation - I believe there is a mismatch between email addresses. E.g. old gmail.com addresses used to end with googlemail.com which may be one possible explanation for the problem.
