📃 January 2012 release notes
New in Firefox
The following features are now available in Firefox:
-
<bdi>:
The
<bdi>element isolates text that may have a different text direction from its surrounding text. This prevents the browser's bidirectional text algorithm from affecting or being affected by the direction of the surrounding text. -
<bdo>:
The
<bdo>element overrides the directionality of text, so that the text within is rendered in a different direction than the surrounding text. -
OES_standard_derivatives WebGL extension:
The
OES_standard_derivativesextension for WebGL 1.0 contexts adds the GLSL derivative functionsdFdx,dFdy, andfwidth.
