hey, while I’m on the topic, here are a few quick tweaks that you can use on the User agent.
There are also other pages out on the net that instruct you on how to change your user agent to be the same as the GoogleBot agent. This allows you to get into cloaked sites. Very handy thing to have available.
While we’re on the topic, I should also mention a great site for detecting anything and everything possible about your browser that a host can determine. It is called BrowserSpy, and it is really comprehensive. (Note, just to be explicit, the aforementioned site is not Firefox specific).
