My computer connects to the internet via Verizon FIOS, I don't use a Cable TV hookup or a dial up modem connection. Its not a PC computer using some version of Windows, its a MacPro desktop machine, and I'm using Yosemite (the latest version of the Mac operating system). Some folks use Internet Explorer, the Microsoft web browser. Firefox is the Web browser that started life as Netscape way back when. See - not so hard ... and yeah, I came to computers later in life ... but I am a geekie/techie/engineer kind of person ... I did radio station type electronics in College ...
