SkipMute for Twitch

Browser extension for skipping Twitch VOD sections muted by Twitch Audio Recognition.

Chrome Firefox

SkipMute automatically skipping a muted Twitch VOD section with Undo available

Works while logged out with no Client ID, token, or setup. By default, muted ranges are read from Twitch's player timeline and verified against playback audio locally in the page.

• Inline Twitch player control near the right-side player buttons.
• Automatic skip when playback reaches a detected muted segment.
• Progress badge showing muted segments passed over total muted segments.
• Undo after every automatic skip.
• Skip action after Undo so long muted sections can be re-skipped when the user is ready.
• Zero-setup, audio-confirmed timeline-marker detection.
• Optional official Twitch Helix API credentials.
• Automatic recovery when Twitch rebuilds its player controls.

• Firefox 142+ desktop: manifest.json uses Manifest V2 and Firefox's built-in data consent.
• Chrome 99+: manifest.chrome.json uses Manifest V3, which is required for Chrome publishing.

1. Open about:debugging#/runtime/this-firefox.

4. After edits, click Reload beside the temporary add-on and refresh the Twitch VOD tab.

1. Run npm run package:chrome.

3. Enable Developer mode.
4. Click Load unpacked.
5. Select dist/chrome.

npm run check
npm run package:firefox
npm run package:chrome

Packaging requires Node.js 18+. It uses PowerShell on Windows and Python 3's standard library on macOS/Linux. No project dependencies are required. CI also validates the packaged Firefox extension with Mozilla's pinned web-ext linter.

Outputs:

• dist/twitch-vod-muted-skipper-firefox.zip
• dist/twitch-vod-muted-skipper-chrome.zip

The extension tries detection in this order:

1. Official Twitch Helix API, if the user adds their own Client ID and OAuth bearer token.
2. Twitch player timeline markers, confirmed against the playing audio before SkipMute seeks.

Detection-source and credential changes apply to the open VOD without a page reload. API failures appear in the player control's tooltip.

See PRIVACY.md. The extension does not collect analytics, run remote code, or send data to non-Twitch services.

• Update the version in package.json, manifest.json, and manifest.chrome.json.
• Review the screenshots in store-assets/chrome and listing copy in STORE_LISTING.md.
• Review permissions rationale in STORE_LISTING.md.
• Run npm run check.
• Package both browser builds.
• Enter a VOD through Twitch's client-side navigation and confirm the control appears.
• Test Skip, Undo, and Skip again on a VOD with visible red muted timeline markers.
• Publish a GitHub release tagged vX.Y.Z; CI attaches both packages and submits Firefox to AMO.
• Upload dist/twitch-vod-muted-skipper-chrome.zip to the Chrome Web Store.
