Description

The support for the mode attribute on the <math> element has been dropped with Firefox 70. The attribute had been deprecated since MathML 2 and Firefox 20 in favour of the display attribute. It had been implemented only in Firefox and Safari, and will be removed from the MathML 4 spec. A polyfill is available for legacy documents.
