  • Version 3.1.1

    Released Feb 27, 2026 - 93.17 KB
    Works with firefox 109.0 and later
    This update improves consistency across the UI and settings, especially around ruby color changes and styling.

    There’s also a new “Remove custom styling” setting that turns off extension-applied furigana styling, so sites can display ruby text using their built-in/default formatting.

    We also added Japanese language support and corrected the review link to open the Firefox Add-ons page.
