    Version 2.0

    Released Aug 16, 2026 - 127.22 KB
    Works with firefox 128.0 and later
    The small, no-nonsense extension you love is back! "YouTube Slow and Reverb" is now "Lento"!
    I started this extension as a fun side-project two years ago. Now, with even more free time on my hands, I've rebuilt it from the ground up to work better, look better, and just feel better all round. Version 2.0 release notes:
    • A totally overhauled UI.
    • Bass boost slider.
    • Preset buttons to quickly and easily switch to a "slow and reverb" feel and a "nightcore" feel.
    • New buttons to report bugs and support me on Ko-fi.
    • Backend changes to improve CPU and memory usage.
    • Expanded support for Spotify, Bandcamp, Soundcloud, YouTube Music, and Apple Music!
    • And most exciting of all, Lento is now coming to Google Chrome (hopefully by the end of this week)!

    Thank you all for your love and support. As always, please do not hesitate to contact me with suggestions, bug reports, and any feedback in general.
