I was super happy with the 'send later' functionality. After I updated Thunderbird, it did not work anymore. Very disappointed that I was not warned about this before the update. I should have, sure thing, delayed the update. Now I lost a very important feature...
In general, let there no misunderstanding, I AM MORE THAN HAPPY WITH THUNDERBIRD IN GENERAL.
There is a beta version of Send Later for Thunderbird 78+, which will be released here within the week. In the mean time you can install it using the .xpi package from here: https://github.com/Extended-Thunder/send-later/releases
Also note, there is literally no way for Send Later to know that you are thinking about updating Thunderbird, so it can't warn you before you do that.
To create your own collections, you must have a Mozilla Add-ons account.
