That's the code. Just paste that in place of the URL, hit enter and have fun.
Q: Can I save my changes?
A: NO! This just creates a temporary version to your cache, then allows you to edit that temporary version. The edited version is then deleted when you leave the page or close your browser. If you could save the changes, you'd get fined for thousands of dollars and spend many years in prison for computer hacking.
Q: Is this a real hack?
A: Sadly, no. This just modifies the cached data in your computer. If it were a real hack, I'd be talking to you from prison.
Q: Will I get in trouble for this?
A: If by trouble you mean the government and/or any authorities, then no. If by "trouble" you mean teachers, bosses, parents, etc. Then possibly. They will probably see this as hacking, and take (un)-necessary action. I would suggest doing this at home, or when alone and not being watched by administrators or parents.
Q: Did you design this code?
A: I wish I did! This code was designed quite a while ago, and I had nothing to do with it. I just found it, and made a video about it.
Q: Will this hurt my computer?
A: The code is INCAPABLE of hurting your computer in any way, shape, or form. If the website you visit had dangerous content (viruses, malware, spyware), then you're screwed.
Q: You are so awesome!
A: That isn't a question, but it is a fact.
Q: Will this work for all browsers?
Q: Will this change the website at all?
A: No. As stated in the first question, this only edits a temporary version on your computer. The website is not affected in any way, shape, or form.
Q: How do I make my changes go away?
A: Reload the page. Internet Explorer users can do this by hitting F5. You could also just click the refresh button (works for all browsers). Closing your web browser or going to a different website will also make it go back to normal.
Q: Why doesn't the website work once I've pasted the code?
A: This is because you're editing the temporary version on your computer, so important connections to the server may not be established. Some websites still have functionality, and some don't. It depends on the web content, and the website. If you wish to actually use the website, refer the question right above this one.
