  • Latest version

    Version 2.0.3

    Released Mar 1, 2026 - 321.24 KB
    Works with firefox 142.0 and later
    ✨ New Features
    • Tamil Romanization: Tamil is now romanized locally using practical phonetics (like zh, th, aa digraphs) rather than relying on external API diacritics.
    • Odia Support: Added Odia to the list of supported Indian languages for native-script restoration.
    • Custom Settings Modal: Replaced the clunky native browser alert with a beautifully synthesized, custom Settings UI overlay that perfectly matches the Spotify design system. This also resolves a known visual bug where Firefox dialogs appeared squished.

    🐛 Bug Fixes & Improvements
    • Firefox Cache Fix: Resolved an issue where Firefox's local storage cache would fail to evict old lyrics, preventing unbounded storage growth.
    • Flicker-Free Injection: Eliminated occasional visual flashes of original lyrics during song changes by implementing a zero-latency synchronous in-memory cache.
    • Injection Reliability: Massively improved the reliability of the fetch-interceptor to ensure native-script lyrics (for Indian languages) are consistently restored on the first try.
    • Performance: Reduced DOM observer overhead by dropping aggressive text-node tracking.

    Version 2.0.2

    Released Feb 23, 2026 - 315.68 KB

    v2.0.2 — Native Script Restoration for Indian Languages

    Many Indian-language songs on Spotify display lyrics only in romanized form (e.g. "un peyaryl en perai cherttu" instead of Tamil script) even though the original native-script version exists in Musixmatch's database.

    This update silently fixes that: when a supported Indian-language song is detected, the extension fetches the native-script synced lyrics directly from Musixmatch and replaces the romanized fallback before Spotify renders it. No settings or toggles required.

    Supported scripts: Hindi, Tamil, Telugu, Kannada, Malayalam, Gujarati, Punjabi, Marathi, Sanskrit, Bengali.

    The Romanize and Translate features now operate on the correct native source script, producing significantly more accurate results for these languages.
