Back in my Windows times I used to use Postbox email client which by far had the best Gmail support. One of the minor obstacles, however, was the fact that not every Thunderbird Add-ons was also available for Postbox since it differs slightly from the former. Therefore Add-ons have to be adapted before they could be used in Postbox.

Many especially smaller Add-ons can be easily adapted by oneself and checked for any compatibility problems.

The following guide briefly explains how to do it.

Get the Thunderbird Add-on that you want to adopt to Postbox. Normally it should be a Zip-Archive with the file extension .xpi.
Rename the xpi file to a zip file and extract the Add-on.

Go into the new extracted folder and edit the file install.rdf. Look for the target application tag for Thunderbird which should look similar to the following:

<!-- Thunderbird -->
  <em:targetApplication>
    <Description>
        <em:id>{3550f703-e582-4d05-9a08-453d09bdfdc6}</em:id>
        <em:minVersion>1.0</em:minVersion>
        <em:maxVersion>5.*</em:maxVersion>
    </Description>
  </em:targetApplication>

<em:targetApplication>

<em:id>{3550f703-e582-4d05-9a08-453d09bdfdc6}</em:id>

<em:minVersion>1.0</em:minVersion>

<em:maxVersion>5.*</em:maxVersion>

</Description>

</em:targetApplication>

After this please add the following target application tag for Postbox.

<!-- Postbox -->
  <em:targetApplication>
    <Description>
        <em:id>postbox@postbox-inc.com</em:id>
        <em:minVersion>2.0b1</em:minVersion>
        <em:maxVersion>3.*</em:maxVersion>
    </Description>
  </em:targetApplication>

<em:targetApplication>

<em:id>postbox@postbox-inc.com</em:id>

<em:minVersion>2.0b1</em:minVersion>

<em:maxVersion>3.*</em:maxVersion>

</Description>

</em:targetApplication>

Now save the file and add all files to a new zip archive. Then change the file extension of the archive back to .xpi instead of .zip. You should be done. Try to install the Add-on in Postbox now.
