This doesn't change the language the person is navigating in, but it does change the language that some links go to, which can change the language the user is navigating on.
This occurs in two locations:
  1. Hidden area
    <a class='nav__home' href='/?lang=fr-FR'>
  2. Footer:
<a class="download" href="https://secondlife.com/support/downloads/?lang=fr-FR">Download</a>
Steps to reproduce:
  1. View source of page
  2. Press F5
  3. Notice that these choose a random language from the possible language list
Expected behavior:
These should always be the language the user is currently navigating in
