  <p>I know, the site content is not in english.
  but in chrome, ie, safari and even ff for android i can see the social icons bar on the top-right corner.
   for some reason on firefox on my pc (47.0) the flex-box is invisible. when i test it on local enviroment (i.e. not on server) it's working, but on server, with firefox, the social icons flex-box isn't visible.
  I've already tried all the other suggestions about display: -moz-box; and flex: 1, and many more solutions i found here, but hadn't come to a solution yet.</p>
