QuickFolders Pro 1 Year License


Buy an annual license for QuickFolders Pro to support and grow this extension further. Unlike many Add-ons that stopped working caused by Mozilla's regular breaking changes of the Thunderbird platform, QuickFolders strives to stay compatible with the current version of Thunderbird. We have successfully ported the Add-on for Thunderbird 91 for the ESR period 2021-2022, and are working on conversion to a native mail extension.

Annual License / Premium Features

The license is valid for 1 year from date of purchase. It does not renew automatically.

QuickFolders Pro gives you full unrestricted access to its premium features. It also turns off the donation pages which are displayed on update with the free version of QuickFolders. More premium features can be added during that time, and there may be "premium exclusive" features not visible to free users.

Personal License Key bound to Email Address

The license is for your personal use and is tied to your email address. The email address must be defined as default identity in any one of your Thunderbird accounts. The validation of the email runs offline and the address is not stored on any server nor transmitted during use. With this mechanism, you can have additional email addresses, which do not need a separate key. You can install and use it on multiple email clients as long as they also have the primary address.


QuickFolders Pro will be automatically updated via addons.thunderbird.net as usual. After the license term expires you can renew the license or keep using premium features under same restrictions as free users. "Premium Exclusive" features will require a valid registration key.


If you have recently donated to the QuickFolders project or have done contributory work, such as translating, you may be eligible for a free license key. Contact us via the email button at the bottom of our support pages.
