Why simple things have to be so hard?

Ok, I know I don't normally do this. I don't write a huge journal entry, just to turn around and write yet another one an hour later. But I am frustrated to no end here. All I wanted to do is block one website, xtube, and I cannot do it. It seems I need to get on to the XP DOS Command Window, but I have searched my system and I cannot find it. Firefox does not allow the ability to block one site and I am not wanting to get a third party software solution that I must pay a subscription for to do this. Not only would I need to pay money for it, I would be losing many sites that I do not find objectionable, but they may. Gearfetish.com or Aby.com to name a few, those are not hard core porn sites, but they certainly have adult content on them. I need to wait until my techy friend is on line so I can ask him how to get into the DOS Command window. I have the code I need to insert, I just need into the system! I'll post when it's done and over with, for now I still have access to free porn, :(
