I'm fairly new with Macs and I'm not sure what is causing this problem. About a week ago my Mac started loading webpages very slowly (CNN would take over 5 minutes to load). I have downloaded and occasionally use Firefox and it had the same problem. I checked my internet connection and everything seems fine, my other computer (its a PC) is connecting just fine and loading webpages at the usual speeds. I found online some instructions regarding Safari loading webpages slow they involved deleting the cache, and then deleting a few .plist files in the library. This seems to work, but with a day or so the problem comes back. Does anyone know what could be causing this problem?
