Build me a browser extension that replaces or adds a better PDF viewer using Mozilla PDF.js, with a reader mode focused on comfortable reading.

I want users to open PDFs in the browser and be able to change the PDF colors, including themes like light, dark, and solarized style themes. It should also have simple reading improvements like smart zoom for text and an easy way to show or hide the toolbar so the document has more space, especially on small screens.

Make it work for Firefox and Chromium browsers. In Firefox it can act like the default PDF viewer, and in Chrome it can open PDFs from a toolbar button or right click menu. Add an options page where people can change the PDF viewer and reader mode preferences.

Please keep the UI clean and practical, package it as a web extension, and look up current browser extension and PDF.js docs online if needed.
