Regressed Canvas fails to render emojis on OS X

Published: | Categories: Canvas & WebGL


The Canvas API is no longer able to render emoji characters on Firefox 41 and later for the OS X platform, due to the switch to the Skia 2D graphics library. This broke the emoji detection feature of Modernizr used by WordPress and others. Mozilla developers are working on the solution.

Update: This issue has been fixed with Firefox 46.
