Using Firebug Firefox Extension to manipulate cookie headers

Sure, You can always use webscrap for manipulating HTTP Request, But this method is a lot simpler.

Steps:
1. Install the Firebug plugin for firefox
2. Open it, the icon will be there at the top right corner.


3. Go to the cookies tab, There will be an enable button which you will only need to use once.
4. After Enabling, It will show the cookies sent over to the webpages.
5. You can edit a value by right clicking and selecting Edit.
6. Reload the webpage, and now the new value will be sent as cookie.

Demo:
At Hackthissite.org Basic Challenge Level 10, I was told to bypass a login page with no clue to what the password is. When I observed the cookie sent, There was a variable "level10_authorized" that was set to "no", I just changed it to yes, and voila!!
