Replace YouTube Chat With Twitch Chat by udin

YouTube to Twitch Chat replaces the live-chat panel on YouTube streams with chat from the corresponding Twitch channel.

The extension automatically derives a likely Twitch channel name from the YouTube channel name. When the names differ, you can enter a Twitch channel manually, and the extension will remember that mapping for future streams.

Features

• Replaces YouTube live chat with Twitch chat
• Automatically matches YouTube and Twitch channel names
• Supports manual Twitch channel overrides
• Saves overrides separately for each YouTube channel
• Lets you restore automatic matching at any time
• Handles navigation between videos without requiring a new browser tab
• Provides a simple toggle to enable or disable the replacement
• Works on desktop Firefox and Chromium-based browsers

Privacy

The extension does not collect, transmit, or sell personal information. Channel mappings and preferences are stored locally in your browser.

Firefox note

Firefox’s Enhanced Tracking Protection may prevent embedded Twitch chat from accessing your existing Twitch login. If necessary, you can disable tracking protection specifically for YouTube using the shield icon in the address bar. This may also allow extensions such as FrankerFaceZ to operate in the embedded chat.
