Hi, for some reason the section icons and other icons on this site don't load correctly for me, it just displays the name of the icon instead of the actual icon. Does anyone know how to fix this? https://i.imgur.com/3NYVjnU.png

I think it's because of my firefox extensions or config. List of my extensions: https://i.imgur.com/Kh1fgN8.png and I'm using the ownyourbits user.js config template.

All help appreciated
