Volume Maxer - Volume Booster by OPM

Control your browser audio from one popup with Volume Maxer.

VOLUME AND PLAYBACK
• Adjust volume from 0% to 400% on supported audio and video players.
• Set different volume levels for open tabs and remember your preferred volume for each site.
• Play, pause and mute media tabs without switching pages.
• Resume paused media directly from the popup.
• Use Reset to return to 100% and clear the site's saved volume.

OPTIONAL YOUTUBE AD CONTROLS
Enable Auto-skip YouTube ads to mute detected ads, fast-forward at up to 16×, and attempt a skip when YouTube's Skip control becomes available.

It works in background tabs with the popup closed and restores the preceding sound and playback speed afterward. This feature is off by default and can be disabled at any time. Manual Skip ad controls are also available for eligible ads.

PRIVACY
Your settings stay in your browser. Volume Maxer sends no analytics, browsing history or personal data to the developer. Private-window site preferences are temporary.

PERMISSIONS
Website access lets the extension adjust audio and video players. Tab access supports the media dashboard and mute controls. Navigation access finds embedded players. Storage remembers your settings.

COMPATIBILITY
Requires Firefox 142 or newer. Refresh existing media pages after updating.

Some protected or cross-origin players restrict volume processing. YouTube ad controls depend on the site's player and may not work with every ad format. Increasing volume may cause distortion on some recordings.
