I use Mozilla Firefox. They have an incredible amount of add-ons that can be used for things such as facebook, myspace, yahoo chat, google chat ect. One of my favorites is a sidebar that has all of my chat applications, facebook updates and other social networking items. Mozilla also has tabbed browsing, the ability to create themes, and a wonderful password manager called Sxipper. It is very easy to download. Simply go to their homepage and follow the one screen directions. Then simply click "find add-on's" and you will be given a whole host of wonderful add-on options. Hope that answers your question. Sincerely, Celeste Stone
