## Description

**Sound Adjuster** gives you precise control over audio in Firefox. Boost quiet media up to 5x, adjust bass, mids, and treble with a 5-band equalizer, change stereo balance, switch to mono, or swap left and right channels. Choose built-in EQ presets or create your own settings for supported HTML audio and video players.

Save volume, balance, and EQ preferences for individual websites, create named profiles, and restore your preferred setup automatically. Audio processing happens locally in Firefox, with no analytics, tracking, uploads, or account required. Sound Adjuster is free, open source, and includes light and dark themes plus controls for managing site exceptions.
