Chrome Voger

Chrome Voger is a Manifest V3 Chrome extension that blocks WebRTC traffic and forces YouTube watch pages to the highest available player quality.

The extension runs locally with no popup, no options page, no telemetry, and no UI automation.

Features

• WebRTC blocking. Sets the Chrome WebRTC IP handling policy to disable_non_proxied_udp, and replaces the RTCPeerConnection, webkitRTCPeerConnection, and RTCDataChannel constructors with stubs that throw SecurityError. The content script runs at document_start in all frames, including about:blank, blob:, and data: descendants.
• YouTube quality enforcement. On YouTube watch pages, selects the highest exposed player quality (up to highres for 8k content) and reapplies the choice after same-tab navigation and loadedmetadata events.

Install

1. Clone or download the repository.
2. Open chrome://extensions in Chrome and enable developer mode.
3. Click Load unpacked and select the repository root.

The extension activates automatically and requires no configuration.

Permissions

The extension declares only the privacy permission, which is required to set the Chrome WebRTC IP handling policy.
