Some television programs are streamed over the internet, either in real time or on demand. Try visiting the website of your favorite stations, or sites such as Hulu. Or to pull in over-the-air digital television broadcasts in your area, you can get a television tuner device (for example, a device that connects to your USB port). You could try searching around for more information. If you run into a problem using Firefox on a particular site, please post back for further advice.
