Since Firefox 38 will be implementing ruby annotation support, there won't be anymore updates on HTML Ruby. Firefox will be the last of the major browsers to implement ruby annotation, but it looks like Firefox will have the best and most complete implementation yet.

Thank you to all HTML Ruby users during the past almost 7 years since I first published it. Special thanks to those that helped develop HTML Ruby by testing, submitting bugs, and suggesting improvements.

HTML Ruby for Firefox

HTML Ruby adds crude support for ruby annotation in Firefox. Both basic and complex ruby annotation in (X)HTML and HTML5 are supported. Writing mode and CSS3 ruby module is not supported.

Download and Install

Download both Mozilla-approved release and cutting-edge development versions for Firefox from Please uninstall or disable XHTML Ruby Support while HTML Ruby is enabled (and vice versa) to avoid conflicts.

You can’t perform that action at this time.
