Version 1.2.0 added support for creating Ebooks with chapters. There's now an additional "Add as a chapter" button and a subpage for managing chapters of the Ebook.
To start using this feature, follow these steps:
-
Browse to the page you want to add as the Ebook chapter and click "Add as a chapter".
- The chapter count will show up on the right side of the button. That number is also a button that opens the chapter management screen.
-
Keep browsing to the pages you want to include in your Ebook and adding them using the new button.
-
Once you're done adding the chapters, click on the chapter count button - this will open the chapter management screen.
-
The cover image is a carousel showing the generic cover by default, but you can change it to any cover from the added chapters you want.
-
The cover title also can be changed - just click on it and edit it.
-
Then, scroll down to see the chapter list and manage it.
-
Each chapter name can be edited by clicking on it.
-
The chapter list can be also reordered using the triangle buttons on the left.
-
Each chapter can be deleted with the "X" button on the right.
-
There's also a "Delete All" button at the bottom which clears all chapters to start again.

-
Once you're done with your edits, click on the "Download X Chapters" button (the X will be a number of chapters added) to get the file.

The extension is available for most of the modern browsers:
- Firefox
- Chrome, Brave, Vivaldi
- Edge
- Opera - waiting
- release the extension for mobile (Firefox)
- adding multiple language support for the extension
adding config page- implemented- customizing the title page in the Ebook (adding a cover image)
There are no configuration options yet, but it's on my roadmap.
The extension utilizes npm build scripts to use custom build configurations for each supported browser.
Running npm run build builds the extension for all browsers. The result is stored in the src/dist folder.
Running npm run clean cleans the dist folder. The dist folder is also cleaned before every build.
The extension can be also zipped and prepared for distribution (uploading to extension stores) using npm run release.
This will build one zip file for each standard (Firefox and Chromium).
Please submit any problems you find on the GitHub page.
Propositions for new features are welcome. Please submit them on the GitHub page.

- The extension is utilizing the Readability library to generate the Ebook content. It's the same library that is used by Mozilla Firefox in the Firefox Reader View.
