Ever since yesterday, my firefox has been not showing certain links or pictures, usually a site logo or menu. I have tried refreshing and turning off add-ons. The links still work, but I just can't see them.
Re: Why won't firefox show certain pictures or links?
So, if you had the same problem that I had, it turned out to be a missing html tag in the overall link. Apparently the older version of Firefox (v3.xx) and other browsers were able to still properly read the code but Firefox 4.xx and even Chrome would not read it. Check that you have the proper closing "/" tags in your code.
