For some reason, pages that I try to refresh in both Firefox and Safari do not refresh when I hit refresh as well as Fn+F5. This is happening both while I am at home and at work (I take my MacBook Pro back and forth between the 2 places).

I am working on a website that is hosted on GoDaddy (I hate GoDaddy by the way). Could this be a global setting on my MacBook Pro or could it be something with GoDaddy?
