How to access any Website or forum without registering.

 All websites and forums will block unregistered users, but they won’t block Google Bot. What we will do is to switch our User Agent to that of Google Bot and freely browse any website or forum without registering.

First grab the add-on for Firefox called ‘user agent’ Here and install it. Now go to Tools > User Agent Switcher > Options and then again to Options.

User agent for Firefox

                         Chrome

User agent switcher options Select User Agent from the left sidebar and click Add. Now in the description field type:

• crawl-66-249-66-1.googlebot.com 

and in user agent field type:

• Googlebot/2.1 (+http://www.googlebot.com/bot.html)

As shown in the screenshot below.
