OK this one might be hard to get. But in the end it is really simple, the biggest problem is how to figure out what should you use.
If you tried several things from previous hackthissite.org missions you probably figured that nothing will work here. So you came here to find new approach. And here it is! If you haven’t figured out from the very name of this mission what you should do is use cookies.
Cookies are small chunks of data saved on your computer by remote server you are accessing. You can read more on provided web site.
Also I suggest using following tools to complete this mission.
First one is Firebug, highly usable development tool for firefox. Second one is Firecookie this one is extension on Firefox extension. So you’ll have to install both plugins.
Now when you are ready open firebug tab named cookies and refresh page of 10th mission. When you’ve done that search for cookie named: level10_authorized when you find this cookie you may notice that value it contains is No, so just double click on cookie name and change value to Yes and continue with any password.
You should be now authorized
