How To Read E-Books on Chrome & Firefox

E-book readers have gained more and more popularity in recent years. However, not everyone wants to buy an Amazon Kindle or Sony E-Book Reader. That doesn’t mean you have to relinquish reading e-books

Thanks to digital publishing solutions, apps for Android tablets or smartphones, iPads, or iPhones enable you to read electronic books on mobile devices. Additionally, there are just as many programs you can download to read e-books on your computer or laptop. But what if you don’t want to install a CPU- and memory-consuming program?

For those who prefer a clutter-free computer, we’ve gathered 8 browser extensions and apps for Google Chrome and Firefox that let you read EPUB files stored on your hard drive. EPUB is one of the best and most common e-book formats, ideally suited for this purpose, and supported by many digital publishing services.

EPUB Reader Extensions & Apps for Chrome

To open newly installed Chrome apps, simply type chrome://apps in the browser’s URL field. You'll see all your Chrome apps in one place—just click to launch them.

You can find the following apps and extensions via the Google Chrome Web Store:

1. Simple EPUB Reader

A Chrome app that also works offline—no internet connection required. It features a library for managing your books, a backup system for recently opened titles, and customizable reading settings (font size, text and background color). The chapter list is easily accessible, and keyboard shortcuts help with navigation.

Unfortunately, features like "Text to Speech" and file conversion (e.g., PDF to EPUB) are not reliable and may require extra installations. Therefore, we don’t recommend using this app for file conversions despite its promising claims.

2. Cloud ePub Reader with Drive

3. Readiator EPUB Reader

4. MagicScroll Web Reader

5. Readium

6. EBook Offline Reader

7. Livemargin Reader

EPUB Reader Extensions & Apps for Firefox

EPUBReader is a Mozilla Firefox add-on for reading e-books directly in your browser—even offline. It launches from the toolbar and gives you access to a catalog of uploaded EPUB files.

Once a book is opened, users can navigate by chapters, set bookmarks, and save copies. Customization options include font size, typeface, link appearance, margin width, and more—offering a streamlined reading experience powered by digital publishing services.
