Which of Firefox and Microsoft Edge support MathML better?

This is just the view point looking at just one example and must not be construed to apply to whole of MathML. You may review some basic MathML information here.

Here is an example of displaying a matrix using the presentation elements of MathML. Browsers do not support MathML the same way, some do better than others. Generally speaking browsers that support HTML5 should support MathML to some extent. This post considers only the latest versions of Firefox and Microsoft Edge at present.

What is MathML?

ML stands for Markup Language and MathML is the markup you can use in web pages (html for example) to display mathematical equations, expressions etc.

MathML is the XML standard for encoding mathematics. It is not just for incorporating mathematics into web pages but also for communicating and exchanging mathematics in mathematical and scientific applications. While most browsers would implement MathML from a standards view point Chrome wanted to have its own way of implementing MathML. However check with the latest version of Chrome for its MathML support.

 The earliest MathML specification is at least some 8 years old. MathML is quite widely used in print books, eBooks, etc. It is also used as an exchange format to support mathematical symbols and content in Microsoft Word, Open Office etc. With all kinds of sensors entering the web by way of Internet of Things, I am positive MathML will be used more widely than at present.
