Still works fine with Firefox on Windows 11, as of 2025-02-10. The trick is to refresh the page for one more time :) Enjoy!

This addon opens local .ipynb files and renders them completely offline. To do this, it builds on existing open-source components like an iPython notebook parser (notebook.js, https://github.com/jsvine/notebookjs) and math rendering engine (katex.js, https://github.com/KaTeX/KaTeX). There are sometimes rendering differences for unusual notebooks but in general this works very well.

Great Work @Rushikesh.

Works really well.
At first I think this add-on didn't work, because slow load the file, but after a while, it's work like magic.
Thanks again Mr. Rushikesh and team, Good job

I was surprised it actually worked, since I thought it was a tall order for a browser extension. However, it worked, and worked fairly well.

Great !

Very useful add on . Saves a lot of time of starting a jupyter notebook server to browse the ipynb files.

Great application as expected from a developer like Mr Rushikesh.
Thank you for making our work easier
