List of urls that won't work

For some reason, again, some urls simply won't show up in my Firefox browser window. Just for fun, I'm going to try and compile a list of urls that don't load. Hopefully, there'll be someone who will be able to determine what the common denominator is for all the sites.

The problem: Every time this happens I have to start internet explorer and repaste the url into the ie url bar ... which is a pain, mostly because you have now navigate using two browser apps and ie doesn't have 'tabbed browsing'.
