I haven't started converting Mail Redirect for Thunderbird 78, as it involves a major rewrite, and much of the functions and UI I need were still changing. Now that 78 is in Beta and support for WebExt Experiments has become somewhat clear, I probably could start rewriting, but I won't be anywhere near finished when Thunderbird 78 is released.
