rtl-reader-view

Screenshot

Vertical reading mode for Firefox. Activate Firefox's reader view and then use this to convert it to top-down, right-to-left.

This is mainly a proof of concept. Not all vertical text CSS rules are supported by Firefox yet: see the draft specification and Styling vertical Chinese, Japanese, Korean and Mongolian text for details.

Usage

See the project page.
