A fantastic add-on for Thunderbird, but it needs a much faster update process. This has happened many times before, that this plugin would not work after an update from Thunderbird. You can simply change the manifest.json file to something like: "strict_max_version": "150.*" then the plug will work perfectly. Later you can check for compatibility. I do this every time but for people with not such technical abilities, this will always be a problem.
