When searching for something in the Firefox browser, I want to customize the keybindings to cycle through the pop up suggestions (see picture for reference). In Chrome, I use
Control-n for down, and
Control-p for up.
In Firefox, what are these keybindings called, and how can I customize them? The default settings are the
down arrow keys, which I don't prefer because I have to leave the home row of the keyboard. For reference, I am on MacOS High Sierra and using Firefox Quantum 62.0.2 (64-bit).
For context, this question exists already, but didn't get any traction.
