I think Bottles has a ready-made profile for installing FL, last I saw it was marked as silver quality. Might be worth a try? I’m a Bitwig user so I haven’t needed to try it. :p (Though I have heard tales of FL’s magnificent piano roll.)

Except in very rare configurations (i.e. not 99.9% of residential), you do not want to have multiple paths to ground within a system. All grounds should go to the tied ground/neutral bus in the main breaker panel, which then goes to earth via a ground rod or a clamp to a copper gas/water line, etc. Otherwise you can have current flowing in ways that the system isn’t designed for, which at the least can trip breakers and GFCIs, and at worst exceed the rating of the wires in a short condition and cause a fire.

I use a fork from F-Droid called Fennec. I’m not sure off the top of my head how closely it tracks with upstream feature-wise but I know it strips out all of Mozilla’s tracking components and it’s always updated within a couple days of the upstream release.
