TabDSP 1.0.2 is here. Install from the Firefox Add-ons store or the Chrome Web Store for automatic updates. Older signed builds remain archived below.
v1.0.2 July 2026 Latest
First-run experience & correctness update to v1.0.1. Clearer first-run onboarding — locked modules now read as gated rather than broken, a calmer resting state, an explicit Free-tier contents line, and a first-enable hint — plus accessibility fixes and license activation that fails closed on unrecognized purchases. No audio-path changes. Install from your browser's store for automatic updates.
