I'm new to Mac so please be gentle! I've just added a couple of entries to my HOSTS file to test whether it works the same way in Mac OSX (SL) as it does in Windoze. I've found it does... and it doesn't. My 4 test entries are totally blocked if I use Safari, but they're NOT blocked in Firefox. Could someone tell me in simple terms why this is so, and if there's something I can do to make Firefox obey the HOSTS redirects? Thanks!
