Visit any forum or website to find something useful and they will ask you to register. Every time a forum asks me to register, I simply close the site. You would probably do the same. But this time, lets face it.
Before I begin, you should know how things work. 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.
Select User Agent from the left sidebar and click Add. Now in the description field type:
and in user agent field type:
as shown in the screenshot below.
Select Google Bot as your User Script by going to Tools > User Agent Switcher.
Now browse any website or forum without registering. Alternatively you can also check out BugMeNot, it is a free online service where people share login information of thousands of websites and forums. Enjoy!
