Disguise as GoogleBot to get free entry to pay sites

See here.
Steps are not clearly defined but what I did is:
1) In Swiftfox, install Add-On "Agent Switcher".
2) Go to Tools>Agent Switcher and click Add
Add in just the Name and the Description: Name =Google; Description =Googlebot/2.1 (http://www.googlebot.com/bot.html) . Then Save/OK
3) To use, goto Tools and mouse over Agent Switcher and pick Google or whatever you called it. Surf to wherever you want.
