QuickFolders Standard 1 Year License


Buy an annual license for QuickFolders Standard 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 now successfully ported the Add-on for Thunderbird 91 for the ESR period 2021-2022, and are working on conversion to a native mail extension. To additionally get the premium feature set, check out the Pro License.

System Requirements

To use a Standard license you have run QuickFolders 5.7 or later. This runs only from Thunderbird 78 forward, older version of Thunderbird are not supported.

Annual License / Standard Features

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

QuickFolders Standard gives you full unrestricted access to its standard features. It also turns off the donation pages which are displayed on update with the free version of QuickFolders. Most importantly, with enough users supporting this Add-on through a license, this guarantees it always being up to date and to work with the latest version of Thunderbird.

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 will be automatically updated via addons.thunderbird.net as usual. After the license term expires you can renew the license, upgrade to QuickFolders Pro for the full premium features or keep using the unfunded feature set.
