BoomPilot by BuLo

BoomPilot gives every tab its own volume control. Turn down a loud video, boost a quiet podcast, or mute one tab without touching the others.

WHAT YOU CAN DO
• Set any tab's volume from 0% to 500% with a live slider.
• Jump straight to 0, 50, 100, 200 or 500% with one click.
• Add Voice boost for clearer speech, or Bass boost for more low end.
• Mute or reset the current tab instantly.
• See every tab you've changed in one list, then switch to it, mute it or reset it.
• Spot changed tabs at a glance: the toolbar icon shows the volume whenever it isn't 100%.
• Pick a light or dark theme.

HOW IT WORKS
BoomPilot adjusts the audio and video players on the page. Nothing is processed until you change a setting, so pages you don't touch play exactly as normal.

GOOD TO KNOW
• Works on regular websites (http/https). Firefox doesn't allow add-ons on its own pages, such as about: pages or the add-ons store.
• Settings last until you close the tab or restart Firefox.
• On a few sites that load media from another domain, boosting can silence playback. Reloading the tab restores the sound.
• Very high boost levels can distort, depending on the source audio.

PRIVACY
BoomPilot collects no data and makes no network requests of its own. Everything stays in your browser.
