  description

  A lightweight extension that puts video and podcast playback speed
  behind a single keypress — no more digging through player menus.
  
  Slow down, speed up, or return to normal with a single key.
  Works on YouTube, Netflix, podcasts, online courses, and other sites
  that use HTML5 media.
  
  ━━━ Only 3 shortcuts to remember ━━━
  
    • Slow down   (default: S)
    • Speed up    (default: D)
    • Toggle 1.0x ⇄ your target speed (default: G)
  
  That is all you need to learn. No menus to navigate.
  Each action can be rebound to any A–Z or 0–9 key.
  
  ━━━ A speed indicator that stays out of the way ━━━
  
  So it does not disrupt your viewing, the speed indicator
  (such as "1.50x") appears at the center of the screen for just a
  moment when you change the speed, and fades out in about 0.3 seconds.
  
  You can confirm the current speed at a glance, without opening the
  player's settings menu. It also works in fullscreen.
  
  ━━━ Speed persists across sessions ━━━
  
  Once set, your speed is retained across tab switches, video changes,
  and browser restarts.
  
  Settings are stored via chrome.storage.local only. They are not
  synced to a Google account, and they do not leave your device.
  
  ━━━ Re-applies speed when sites reset it ━━━
  
  YouTube and a few other sites silently reset playbackRate to 1.0x
  after an ad, a seek, or a quality change.
  
  This extension watches for those moments and reapplies your chosen
  speed automatically.
  
  ━━━ Embedded players, audio, local files ━━━
  
    • YouTube / Vimeo / SoundCloud embeds in blog posts
    • <audio> elements — podcasts, audiobooks, web radio
    • Video files opened locally in the browser
  
  The same shortcuts and HUD apply everywhere.

  What this extension does NOT do:
  
    ✗ Send analytics
    ✗ Show ads
    ✗ Contact remote servers

    ✗ Read page content or form input

  ━━━ Permissions (kept minimal) ━━━
  
    • storage     — to save your settings locally on your device.
    • activeTab   — to read the current tab's URL when you open the
                    popup, for the "exclude this site" toggle.
    • Host access — so the content script can find <video> / <audio>
                    elements on the pages you visit.
  
  ━━━ A few additional details ━━━
  
    • Shortcuts auto-disable while typing in text fields
    • Modifier keys (Ctrl / Alt / Shift / Meta) are ignored, avoiding
      collisions with browser or site shortcuts
    • Step size is adjustable in 0.01 increments (useful for language
      learning)
    • Any single site can be excluded with one click
    • Speed up / slow down also updates the toggle target, so the speed
      you fine-tune while watching becomes the toggle destination
    • Popup UI switches between English and Japanese automatically
  
  ━━━ Open source ━━━
