Misleading error on firefox

[PastelStoic]

Firefox does not support the webserial api, causing connections to a device to fail, but the the error message unhelpfully reads "TypeError: navigator.serial is undefined", followed with a "Is your device maybe pre-CCOS?" which leads users into thinking their device is defective. This error should be caught and handled with a specific message saying that firefox is not supported, and that a chromium-based browser (Chrome, Edge, Brave, etc) should be used to connect to your device.
