Postbox Add-Ons and Dictionaries
Postbox provides a mechanism that allows add-ons from 3rd party developers to be installed within the application. Add-ons extend the functionality of Postbox in ways that provide additional benefit and control over your email experience.
Unmodified Thunderbird add-ons do not work within Postbox, but developers of existing Thunderbird add-ons can port their add-ons to Postbox (see Note to Developers). If there is a particular add-on that you would like to see in Postbox, please contact the add-on developer directly to request compatibility with Postbox.
Trouble-Shooting and Support
Please note that add-ons can change the DNA of Postbox in ways that are incompatible with its default behavior. If Postbox is not operating the way you expect, our recommendation is to temporarily disable add-ons to see if the problem clears up for you.
Postbox does not support the functionality of 3rd part add-ons, as it is up to each developer to support the functionality of the add-ons they author. If an add-on is not working correctly, please contact the add-on developer directly.
Installation
- 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".

Note to Developers
Here are a few resources that you may find helpful to your porting efforts:
- Postbox is based on Mozilla Thunderbird, but Postbox is not open-source. But you can find some of the code here http://postbox-inc.com/coveredcode. (People trying to port Thunderbird add-ons have found this useful.)
- For a version of the DOM Inspector that will work with Postbox 3.0, see http://download.getpostbox.com.s3.amazonaws.com/addons/inspector/inspector-2.0.9.xpi
- For a version of the JS Debugger (venkman) that will work with Postbox 3.0, see http://download.getpostbox.com.s3.amazonaws.com/addons/venkman/venkman-0.9.88.2.xpi
- To make an add-on for work for Postbox 3, you'll need to add this in the extension's install.rdf file:
<em:targetApplication> <!-- Postbox --> <Description> <em:id>postbox@postbox-inc.com</em:id> <em:minVersion>3.0</em:minVersion> <em:maxVersion>3.*</em:maxVersion> </Description> </em:targetApplication>
