About a 1/3 of the way through the blog video tutorial when he it is talking about creating the 'Comments' link, I do just as the video says but when I click on the link I get an error popup in Firefox stating 'Firefox doesn't know how to open this address, because the protocol(localhost) isn't associated with any program'
