Hyperlinks?

The Blue Colored Text that you can click and you will be directed to a website. How do you make those using Mozilla Firefox 3.5.5? I can not for the life of me figure out how to do that. I tried playing around with the hyperlink button that can be found right above the winking smiley face and the cheesy grin button to no avail. Any assistance would be appreciated. Thanks,
