Change browser User-Agent (firefox)

  I have been using Wireshark a lot in recent times not only for my school projects but also because it fascinates me and scares me how much insecure the web is today. One of the awesome things I found when I was going through a Wireshark capture was that the packet gives us all the information we require to know.
When I captured a HTTP packet I could read everything that is being sent and recieved though not eveything was in cleartext. But I found that the name of the browser was in Cleartext and wondered if I could fool a server in thinking that I am using a Internet Explorer when I really was using Mozilla.To do this go to the “about:config” in your Mozilla browser and there right click select new and enter the string “general.useragent.override” and then double click on it and enter whatever you want as the name of your browser. And now when you capture the packets you will see whatever you have entered in place of your browser name.
