Postbox Add-ons
Postbox now contains add-on capabilities. We are currently focused on helping add-on authors make their existing Mozilla based add-ons compatible with Postbox. If you are an add-on author and would like to make your add-on compatible, please contact us at and we'll be happy to help!
Installing an Add-on within Postbox
- Download and save the add-on to your hard drive. (Firefox users, be sure to right-click the download link, then select "Save Link As..." from the contextual menu.)
- In Postbox, go to Tools | Add-ons.
- Click the Install button and select the file you downloaded and click "OK".

Compatibility and Support
Postbox provides a mechanism that allows add-ons from 3rd party developers to be installed within Postbox. However, it is up to each add-on developer to support the functionality of their add-ons they author. Postbox does not provide support for 3rd party add-ons.
Unmodified Thunderbird add-ons do not work within Postbox at this time. Developers of existing Thunderbird add-ons need to port their add-ons to Postbox. Sometimes this can be as simple as changing a few parameters, such as product, version, etc., other times the porting effort may be more complex.
In some instances, such as Lightning, Postbox has performed the necessary porting work to get an add-on to operate within Postbox. We do this so people can get an early feel for how key add-ons will function within Postbox. But we do not support these add-ons, again, because we did not develop them.
We work with extension developers as much as possible, but if there is a particular add-on that you really like, our suggestion is always to contact the add-on developer to have them port their add-on to Postbox.
