I have made the necessary changes in following two files:
https://github.com/mozilla/fireplace/blob/master/src/templates/footer.html

I have tested the changes locally using the local flue server and damper.
`font-weight: 300` matches the other links in the footer, but it makes the `font-weight` inconsistent with the other fields on the "My Account" ("Account Settings") page.
