What would be the advantage of that? Functionally that is the same as tapping the application menu and then choosing 'settings'.

If there is something specific you would like to see exposed in about:config that is currently not available in settings, let us know.

Sorry, I didn't mean that it would be an actual feature request. The grandparent poster wanted about:config and I proposed that it do that. I don't actually think it has any advantage overall.
