A must-have add-on that unfortunately stopped working with TB 136.

A big thanks to @the-nic who provided a working solution, and to @trashbasu for offering more complete instructions for those unfamiliar with editing add-ons.

It should be noted that the developer has previously stated that they ONLY support ESR (Extended Support Releases) of Thunderbird, which 136 will eventually become, perhaps later this month or in early April.
