User reviews

Python Notebook Viewer is praised for allowing offline rendering of .ipynb files in Firefox, providing convenience without a dedicated app or server. Many users find it useful and well-done for typical notebooks. However, the extension has not been updated since 2019, leading to bugs such as text visibility problems (especially with dark mode), incomplete rendering of certain elements, and inconsistent behavior on recent Firefox versions or OS platforms. Despite some quirks like slow load or needing page refresh, it remains a valuable tool for quickly viewing notebooks locally.

Pros

Enables offline viewing and rendering of .ipynb files directly in Firefox without needing Jupyter Notebook server.
Works fairly well for most notebooks, with good support for math rendering via KaTeX.
Simple and convenient tool that saves time opening Python Notebook files without dedicated applications.
Generally appreciated for the ease it brings to viewing notebooks and as a helpful utility overall.

Cons

The extension appears abandoned with last update in 2019, leading to bugs and outdated support.
Text rendering issues occur, especially with dark mode themes causing white text on light backgrounds that is hard to read.
Some notebooks do not render properly and some math symbols may not display correctly.
Slow loading times for some files and occasional requirement to refresh the page for proper rendering.
Does not work reliably on some newer Firefox versions and operating systems, sometimes just rendering JSON instead of formatted notebooks.

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.

Extension safety

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Python Notebook Viewer requires very minimum permissions.

Risk impact analysis details

High Injects scripts into web pages, which may alter or extract site contents, resulting in a substantial risk.

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Browser Add-ons, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Python Notebook Viewer is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
