1. First install nodejs at your system using https://nodejs.org/en/download/

2. Then using npm package manager which comes with nodejs; install firebase with the help of this url https://www.npmjs.com/package/firebase-tools

As Lalit said install first node.js then make sure that make sure that this went well by typing

node -v

and

npm -v

if these two tests went well install firebase as the following:

npm install -g firebase-tools

and since you are new please try copy past commands until you get used to them.
