This software is being mentioned for people who want to try it. You will notice that I DID mention in my original post that it is NOT the release candidate. Your warning is well worth mentioning, and you are correct, Linux is not Windows. The Firefox download comes from MOZILLA. That's the SAME Mozilla that supplies the Firefox in the repository. If you take a look around the forum you'll see that off-site software is mentioned all the time. Linux Lite is an excellent distro for people who are just getting into Linux. But Linux, in general, is also one of the most wonderful things to learn, and try new things. If I couldn't try new things, and learn from my mistakes, I wouldn't use Linux. I'd go back to Windows.
