## Description

MOBI Reader is a user-friendly Chrome extension designed to open and view MOBI (Kindle) eBook files directly within your browser. Simply right-click on any MOBI file link and select 'View MOBI' or use the popup interface to load files via URL or drag-and-drop. It supports offline file loading and features a dark mode for comfortable reading in low-light environments. The resizable popup window dynamically adapts the content layout to enhance readability.

Built using an open-source JavaScript library (mobi.js), MOBI Reader ensures smooth rendering of MOBI files without the need for external applications. This extension is ideal for Kindle users or anyone needing quick access to MOBI documents without leaving their browser. For feature requests or bug reporting, visit the official extension homepage.
