Enterprise policy descriptions and templates for Thunderbird

The templates of a newer version of Thunderbird usually also work with older releases, but they may contain policies which older releases don’t support. We suggest using the templates which correspond to the version of Thunderbird you are deploying.

List of supported policies

The following table states for each policy and setting since when Thunderbird supports it, when it was removed, and whether Firefox supports it.
