I can get the FireFox Setup 19.0 downloaded but it will not install in my Windows 8. In fact I can't get anything to install in Windows 8. Any solutions will be greatly appreciated.
Firefox should be compatible. What error message are you receiving? Do you have any firewalls blocking the installation? Have you tried a reboot of your computer?
I wonder if you software Firewall or likely your antivirus client interfering and corrupting the download.
