The MathML Recommendation offers two flavors of markup: presentation MathML which describes the visual rendering of mathematical formulas and content MathML which encodes their meaning. While Gecko has supported the presentation flavor for a long time, the content flavor has not been implemented so far. David Carlisle, from the Math WG, has written an XSLT stylesheet to convert content MathML to presentation MathML. This add-on allows to render content MathML by applying this stylesheet to each <math> fragment on a page.
Compatibility: Gecko 16 or greater. The add-on may also work on older versions.
Licenses: The add-on code is licensed under MPL 2.0.
