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.

As of 2023, does not work anymore.

Doesn't render the ipynb when opening as a web page but instead requires downloading it and then opening the file

Not working on 96.0.3 (64-bit) Linux :-( (just renders the json)

Does not work

I have the same problem - text is displayed in white, that means I can't read it, which is quite a problem. Besides that, a very helpful tool, if I could just read the text :)

Everything's great except that it suddenly displays text as white so I can't read them. Really convenient though.

Overall great simple extension for opening Python Notebook files without installing a dedicated application! However it seems that the app is abandoned (Last updated: 2 years ago, Mar 11, 2019). So for that it gets 3 stars, and it is a bit buggy. Namely, some math symbols do not show up properly. Also if you're using a Windows OS and your default theme for apps is 'Dark' the text will show up very light on a light background making it very difficult to read.

Great Work @Rushikesh.

Does not work

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.

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
