Converter from content MathML to presentation MathML

Features & Capabilities

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.

Is Content MathML Polyfill Safe?

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.

Content MathML Polyfill requires a few sensitive permissions. Exercise caution before installing.

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 Add-ons Store, 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.

Content MathML Polyfill is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
