I run Windows 10 and I have never done anything with Profiles at all. I am completely new.

When I go to about:profiles I see three Enteries,

  • Profile: default-release
  • Profile: default
  • Profile: dev-edition-default

Of which default-release seems to be default. Indicated by Default Profile: yes

First off, why are there 3 profiles if I never created one?

In Each profile, there is Root Directory and Local Directory which point to the same directory in all 3 cases. What are the differences?
