Do you genuinely there's several times more MAUs deliberately using "backspace for back" than literally any other keyboard shortcut?
It seems obviously implausible to me.

It's also worth pointing out there isn't a great opportunity to learn the keyboard shortcuts Firefox provides. Traditionally you'd learn shortcuts by seeing them next to menu items, but the menus are hidden behind the Alt key, and many actions simply aren't listed there. For example, "Find Again" / F3 is omitted.
