LiveDub — Gemini Tab Dub от M.Azadegan

LiveDub captures the audio of a browser tab and streams it to Google's
Gemini Live API for near-real-time translated dubbing — using your own
Gemini API key (bring-your-own-key, no account or subscription with
this extension).

How it works
1. Click the toolbar icon to open the dubbing panel.
2. Add your Gemini API key in Settings (stored only on your device).
3. Pick a target language and click "Start dubbing…".
4. Choose the tab in Firefox's built-in share picker and make sure
"Share audio" is checked.
5. Hear a live translated track while the original page keeps playing
(optionally auto-muted).

Privacy: audio is sent directly from your browser to Google's Gemini
API with your key — never through any server operated by this extension's
developer.

Requires a Gemini API key with Live API access from Google AI Studio.
