I use both browsers at home (on Macs) and at work (on a PC) and I know what you are talking about. I don't think it is the browser. I think the web site is not loaded correctly on the host so no information appears. I could be completely off on this, but I find that I see this occurrence most often when I am opening a page with "breaking news" (sports or news media), leading me to believe it is not the browser.
