    Version 7.5.52

    Released Sep 28, 2026 - 4.7 MB
    Works with firefox 128.0 and later, android 128.0 and later
    Version 7.5.52 - Kitsumi grew from a simple subtitle overlay into a full language-learning toolkit: a reader for articles, text recognition in images, a reworked YouTube integration and many new ways to study. Performance passes keep it light on CPU and memory, the look got a full theming overhaul, and the interface now speaks 20 languages.

  • Version 7.5.50

    Released Sep 26, 2026 - 4.66 MB
    Works with firefox 128.0 and later, android 128.0 and later
    Version 7.5.50 - Kitsumi evolved from basic subtitle overlay into a full language-learning toolkit, getting new fresh design overhaul, adding flexible per-row segmentation strategies, an Articles text reader (hover/click/selection modes), OCR (built-in + Tesseract.js with drag-and-drop and right-click support), and a heavily reworked YouTube integration with multiple display modes and cross-language cue-contamination fixes. Alongside new features, I ran major performance passes-fast-exiting content-script init in video-less iframes, speedifying lazily-loading modules, and fixing delay/offset persistence bugs on auto-load to keep CPU/RAM low and reliability high. The UI also got a full theming overhaul for that spicy theme-aware color-mix variation; finally expanded localization to 46 languages.
