About this extension
Sound Booster VMax makes a quiet tab up to 600% louder. Click the toolbar icon, pick a level with the slider or a one-tap preset, and the tab you are on gets louder right away.
When a video, song or podcast is still too quiet at full system volume, the browser's 100% limit is what stops you. Sound Booster VMax sends the sound of the page's audio and video through a volume booster you control, so you can go past that limit without touching your system volume or your other tabs.
WHAT YOU GET
• Volume boost from 0% to 600% for the tab you are on
• Presets for 100%, 200%, 300%, 400%, 500% and 600%, plus a smooth slider
• Number keys 0–6 jump straight to 0–600%
• An on/off switch: off plays the tab at its normal volume
• The level stays with the tab after the popup closes, until you change it or close the tab
• The current level is shown on the toolbar icon
• Other tabs playing sound are listed in the popup, so you can jump to them
• Interface in 54 languages
HOW TO USE
1. Open the tab that is too quiet and start playing.
2. Click the Sound Booster VMax icon in the toolbar.
3. Drag the slider or click a preset. Set it back to 100% or switch it off to return to normal.
GOOD TO KNOW
• Firefox's own pages and addons.mozilla.org can't be changed by add-ons.
• Copy-protected streams (DRM) and some audio loaded from other websites can't be boosted: Firefox does not let add-ons process that sound. The popup tells you when this is the case, and such media is left untouched.
• If a page started playing on its own, click the page once (or press play) so Firefox lets the boost start.
• Very high levels can distort the sound and can be hard on small speakers and on your ears. Raise the level gradually.
PRIVACY
Sound Booster VMax needs no account and has no ads or analytics. Nothing about what you listen to or the pages you visit is collected or sent anywhere; the audio is processed inside your browser. The add-on opens its page on newapptome.com after you install it and after you remove it.
