Allow custom shortcuts via System Preferences (e.g. "New Private Window" should be ⇧⌘N)
For those who are annoyed at Firefox on macOS using ⇧⌘P for New Private Window instead of ⇧⌘N, I too, have this issue.
Unfortunately after much trawling around on the interwebs it has led me nowhere except for this sad bug report on Bugzilla.

Thanks for the feedback. This is not the right place for asking to vote for the bugzilla.
