ePUB Reader - A Powerful Add-On for Viewing ePUB Files on Firefox

ePUB Reader is a Firefox add-on that can open and view '.epub' document files. This powerful tool allows users to directly open ePub files via a context menu in the browser or view offline by drag and dropping the file into the UI. Besides, users are given multiple viewing options and can resize the reading area to cater to their preferences. The tool utilizes an open-source JavaScript library 'epub.js' to render the documents. Users can get more information, request features, and report bugs via the add-on's homepage.

This addon gets updates on chrome extensions store (last got in may 2024) but has not got any since 2019 on mozilla firefox addons store, which shows how much addon dev cares about firefox and firefox users. As of now this is not working on zen browser and floorp browser and 135 versions. Lacks TTS feature and more fonts options. Check yourself, people.
