Wikipedia with MathJax is a Chrome extension developed by Boris Gromov. This free add-on falls under the category of Browsers and specifically the subcategory of Add-ons & Tools. The extension replaces Wikipedia's bitmap equations with HTML-CSS equations by re-rendering them using the open-source MathJax library.

One of the main features of this extension is the ability to scale Wikipedia pages without losing equation quality. By left-clicking on an equation, it can be instantly zoomed to 200%, with the option to change the zoom level through the MathJax menu. Right-clicking on an equation brings up MathJax's context menu, which offers additional options such as scaling all equations on a page or viewing the source TeX equation.

The extension is published under the New BSD License, and its source code is available on GitHub. For bug reports and feature requests, users can utilize the Issue tracker on GitHub. Recent updates have brought improvements and bug fixes, including support for chemical equations and adaptations to recent Wikimedia math engine changes.

Overall, Wikipedia with MathJax is a useful Chrome extension for anyone who frequently uses Wikipedia and requires high-quality equation rendering.
