MOBI Reader: Powerful Firefox Add-on for MOBI files
"MOBI Reader" is a user-friendly Firefox extension that enables users to easily open and view .mobi file formats – a popular e-book file format designed for Kindle devices – directly in the browser. It offers a stand-alone pop-up window for viewing the documents and features like dark mode for comfortable night-time reading. The add-on utilizes an open-source JavaScript library, mobi.js, to render the .mobi file format.
