I Just installed Zorin one of Ubuntu distro which I think more familiar because you can choose your desktop theme to Windows 7, Windows XP or Mac OS X. And the important thing is ease to use because the PC is will mostly used by my wife and my kids.
Zorin default browser is Chrome, but I love Firefox. To install latest Firefox on Ubuntu open Terminal (Press Ctrl+Alt+T) and copy following commands in the Terminal:
sudo add-apt-repository ppa:mozillateam/firefox-next sudo apt-get update sudo apt-get install firefox
OK, that’s it and enjoy browsing.
