That is an SVG image and there is probably JavaScript involved.

If you use extensions ("3-bar" menu button or Tools -> Add-ons -> Extensions) that can block (wanted) content (Adblock Plus, NoScript, Disconnect, Ghostery, Privacy Badger, uBlock Origin) always make sure such extensions do not block (wanted) content.

• make sure your extensions and filters are updated to the latest version

This sadly does not solve my problem as I have no add-ons or plugins installed on firefox. I'm using Ubuntu 18.04.1 LTS Update: I know it's been less than five minutes but I just reloaded the site again and somehow, it worked! Thanks for your time!
