I have made the necessary changes in following two files:
https://github.com/mozilla/fireplace/blob/master/src/templates/footer.html
https://github.com/mozilla/fireplace/blob/master/src/media/css/site.styl

I did not remove the anchor tag from the footer.html as it was creating styling issues. Tried to keep minimum changes in this patch.

I have tested the changes locally using the local flue server and damper.
you could then simplify

```css
#directory-footer .group a.region,
form span.region
```

to

```css
.region
```
