Any Hope For A Random Signature In TB 68.3+ ?

[X-Force]

Hi all,
It seems that any extension that allowed a user to have a randomly selected signature inserted (from a predefined list of signatures), like Tagzilla, Signature Switch, or random(signature) have all met their untimely ends. Is anyone aware of a similar extension, or one that is a work in progress? I just need something that will randomly pull a line from a .txt file (or anything), and then insert that line as the signature. Is it even possible with today's Thunderbird?
Thanks!

Nothing new, as Thunderbird evolve, main developers put on side extensions, and the motivated developers with cool extensions give up! And I suppose that the new devs doesn't known what is a mail application as they use online app or phones app.
