If I use arkenfox and make a bunch of overrides, do I need to make sure to back it up and manually install on every fresh installation or does Firefox Sync take care of that?

What about extension settings? Is there a universal rule or is it per extension and up to them?
There is a ability, iirc for extensions to use your Mozilla Sync account for storing settings. However it´s up to each extension developr to include this.
