My MathML Home Page
Internet Browser: All versions of Firefox render MathML. Click the Firefox logo to download Firefox, version 3.
However "To see MathML as intended, you need sufficient font support, which may mean installing some fonts. Just having a MathML-enabled browser is not necessarily enough." To install STIX Beta Fonts, go to http://www.mozilla.org/projects/mathml/fonts/ which is also the source of the quotation above.
Firemath is a great extension of Firefox that makes it easier to generate presentation MathML markup. Click on the Firemath logo to install it. http://www.firemath.info/
Internet Browser: Click the IE logo to download Internet Explorer, version 8.
Then download and install MathPlayer from Design Science to allow MS Internet Explorer to render MathML.
