Audio-Engine (v0.2.0)

What's new in v0.2.0

Firefox / LibreWolf Support

Audio Engine now works on Firefox (140+) and LibreWolf. The audio engine was rebuilt from scratch since Firefox never implemented tabCapture — it hooks directly into <video>/<audio> elements using the Web Audio API.

Chrome Bug Fixes

• Fullscreen — YouTube fullscreen button now works while audio is boosted (no more double-animation or stuck state)
• EQ handles — slider thumbs are now centered on the track
• Cross-origin audio — TikTok, Meet, and other cross-origin sites now work via tabCapture + offscreen
• Stability — fixed crashes on tab switch and extension context invalidation
