About this extension
Boost the volume of any website in Firefox — up to 500% louder than the
default browser limit.

SOUND STUDIO MARI is a lightweight volume booster and equalizer extension
that works on any tab. Whether the audio is too quiet on YouTube, Twitch,
Netflix, or any other site, this add-on gives you full control.

FEATURES:
• Volume boost up to 500% — go beyond the system limit
• Built-in equalizer (EQ) — adjust bass, mids, and treble
• Works on all websites — video, audio, music players
• Applies per-tab — boost one tab without affecting others
• Minimal UI — easy to use, no setup required
• Zero data collection — no tracking, no analytics

PERFECT FOR:
• Quiet videos and lectures with low recording volume
• Music listening with custom EQ preferences
• Accessibility — users who need louder audio output
• Firefox users who need more than the OS volume slider

HOW TO USE:
1. Click the extension icon in the toolbar
2. Drag the volume slider to boost audio
3. Fine-tune with the equalizer bands

Lightweight and privacy-friendly. No permissions to your browsing history.
