It sounds like madness, but Firefox (checked on 82.0.3) on macOS (checked on 10.15.4) doesn't allow tab navigation on the links!
We found it when test how focus-lock helps to keep focus inside the dropdown menu.
At the same time, it works on Firefox on Windows 10.
Use keyboard navigation to move focus between controls
in the System Preferences - Keyboard -Shortcuts and now it works well.
This problem is not directly related to the focus-lock. But let it be there for the next guy who will be close to spending a lot of time to understand why it doesn't work.
