start firefox with multiple pages

I often open the same set of webpages every day, i use firefox. Wish you could have tell me to open more than one homepage open every time i start the browser, each opened in a separate tab?

first Click "Tools" - "Options" then With the "Options" dialog box appears, click "General"; after that Next to "Location(s)" enter your home pages separated by the pipe (|) symbol. For example, the following location will open up detik, Google, and CNN as your home pages: "detik.com|google.com|cnn.com"; last step Press "OK" to save your changes then Close down and restart Mozilla Firefox to see your home pages opened as separate tabs. Enjoy!
