Recently when I visit Facebook and the Mozilla Page on my Desktop Computer (I am writing this on my laptop because this website does not function on my PC) using Firefox, the pages do not display correctly. Instead of the Facebook page appearing in it's usual blue-coloured format it shows as lines of text (not HTML code, but just lines of text, such as "Connect with friends..." in a different font than it should, its all black and white, no colour). Also the top of the screen has written "Facebook Logo" in blue underlined italics instead of the actual logo.
Does anyone know what may be causing this problem? If so, could you provide me with a solution? I have already tried several support topics (i.e. clearing cache, cookies etc.) but this does not help.
Please tell me if you require more detail or wish for me to elaborate/describe my issue in an alternate way.
Thank you very much.

You can also try clearing cache and seeing if a addon is causing a problem, refer to below.
Make sure that you haven't enabled a High Contrast theme in the Windows/Mac Accessibility settings.
Make sure that you allow pages to choose their own colors.
Note that these settings affect background images.
cor-el, I have tried the steps you specified and nothing seems to work, it still appears the same. Thank you though
Did you check the screen color accessibility setting in Windows as well?
