About this Add-on
Note: This addon has been superseded by the built-in functionality in Thunderbird 91.
Source code available on github.
This version sets a strict_max_version of Thunderbird 78.*, so that this addon will be marked as incompatible with Thunderbird 91 at upgrade time. Thanks for sticking with this addon for so many years!
