Firewalls & WordPress

I have an interesting problem and am wondering if anyone else has had it or knows how to get around it. I have just completed designing my site in WordPress – https://www.thegapmedia.com . Everything works fine at home. My issue is with two plugins on the site. In the sidebar I have a “Social Media Widget” which provides links to Social Network platforms I am registered on. At the foot of each page I have a plugin called “Social” which allows viewers to share the content of my page on a number of Social Networking platforms. Naturally in the configuration of these 2 plugins I have to tie up a link to the relevant page with the relevant icon. That’s simple enough and as I said works perfectly. However – at my place of work Facebook is ‘banned’ via their firewall/ organisational policies and cannot be accessed. This is resulting in the 2 Facebook icons in the 2 plugins mentioned not showing and being replaced instead by the word “Facebook” which is not good at all as it throws the alinment out. Is there anyway to work around this. I’m thinking there are probably many people around the world who cannot access Facebook at their place of work and this doesn’t create a very professional image of my site. I am thinking it is obviously because of the link to Facebook’s page. Any idea’s of how I can work around this?

Thanks
