I want to build my own office building. I don't have any construction skills, but I've been in an office. How should I start?

Learn to program first. Don't worry about your browser for a while. You'll need to learn to program first before you can take on anything as complex as a browser.

The current version of the Firefox contributions page lists 2,103 people who have made significant contributions to the browser. Many of these are pros. You might not be able to build something by yourself in your basement as easily as 2000 professionals can do it.

It might be easier to modify a browser to make it do what you want. Firefox allows very interesting (and relatively easy) extension editing, which can be done with variations of HTML, CSS, and JavaScript.

Hope this helps
