    Version 4.1.1

    Released Jan 2, 2026 - 49.88 KB
    Works with firefox 109.0a1 and later
    I added a small fix so my extension will work with amazon prime video - the former HTML element that it was prepended to had it's class name changed, so I instead target a different element instead so it will be more robust to changes.

    Works with firefox 109.0a1 and later
    Update April 2025 - Version 4.1.0
    Added fix for Disney Plus. They had made a DOM change with multiple videos being added, so the speed changing function was targeting the wrong video. The fix has been tested and is working.

    Minor bug fixes

    Update August 2023 - Version 2.0.3
    Now works with most websites that have video, including iframe videos. Please report any sites that do not work and I will look into why.
    Added alternative keyboard keys for changing speed, the two square bracket keys and the backslash key [ ] . Some websites like YouTube change the caption size with the + and - key, so the [ and ] key can be used instead.
    Added finer speed increments of 0.05 for speeds under 1.5x.
