I was able to move my Message Notes to XNote++, another note extension for Thunderbird that also works for TB 68 and higher.
You need to locate your messagenotesplus.sqlite in the TB profile folder to extract the notes. I can add technical details of the conversion if someone is interested.

Very useful Add-on, sad it does not work any more. Can we do something to motivate you to update it for new Thunderbird?
