Clearboost — Volume Boost

Turn up quiet videos, calls, music, and streams to 600% while keeping control of distortion.
Volume booster extensions should do one job. Too many in this category have abused user trust with adware, affiliate injection, tracking, or code delivered after installation. ClearBoost takes the opposite approach: a small, auditable extension with no content scripts and no access to the pages you read unless you explicitly enable optional per-site memory.
