Audio stays local and is never sent anywhere. Your tabs and browsing remain completely private. 🆕 Latest – v2.1.2 (UI Hardening & UX Patch) * Conflict Resolution Engine: Replaced silent tabCapture rejections with a dedicated error state. If another app blocks audio, the UI temporarily locks, flashes a localized warning, and gracefully resets. * Centralized UI Lock: Controls are now strictly bound to the audio engine's connection state, completely eliminating "ghost clicks" and UI wake-ups during the "Initializing..." phase. * Anti-Squish CSS Architecture: Applied strict flexbox constraints to ensure UI elements maintain exact dimensions even when displaying long translated strings. * Perfected Teardown Sync: Eliminated a visual race condition that caused scrolling track titles to overlap into a jumbled mess when toggling the extension off. 📌 Previous – v2.1.1 Highlights * "Anti-Booster" Volume Drop Fix: Re-calibrated the master compressor threshold to ensure standard-volume audio streams are no longer aggressively squashed when the extension is first enabled. * EQ Distortion Prevention: Tuned the limiter with a softer knee and optimized ratio to safely glue frequencies together and prevent harsh digital clipping during heavy bass boosts. * Restored Transient Punch: Reverted attack and release times to their optimal 'magic numbers' (3ms attack, 250ms release) to ensure heavy bass notes retain their physical punch and deep sustain without pumping the vocals.
