About this extension
Turn up quiet Netflix playback beyond the normal volume limit.

Volume Booster For Netflix uses Firefox's built-in Web Audio capabilities to increase Netflix audio up to 500% directly in your browser.

Features:
  • Boost Netflix volume from 100% to 500%
  • Simple volume slider
  • Optional auto-reapply when Netflix changes episodes or video elements
  • Works entirely inside Firefox
  • No accounts, analytics, advertisements, or tracking
  • No personal data is collected or transmitted

How to use:
  1. Start playing a title on Netflix.
  2. Click the Volume Booster For Netflix icon.
  3. Choose your desired boost level.
  4. Click "Enable boost."

For compatibility with Netflix DRM playback, audio boosting is applied after video playback has started.

Audio boosted significantly above its original level may introduce distortion depending on the source material and your speakers or headphones. Increase the volume gradually.

Volume Booster For Netflix is an independent browser extension and is not affiliated with, endorsed by, or sponsored by Netflix.
