Thunderbird + Lightning on FreeBSD

[Rastko P]

I tried compiling Thunderbird from ports, but it's too big, and there
are errors. I'll try to do it some time again, starting clean.


But in the mean time...

Choosing the macOS extension/add-on format seems to be working for the
binary distribution.

Just go to Most Popular add-ons, and Ligthning will be greyed-out. Click
on the "Add" button, and

choose Mac OS X. And it appears to be working.
