Boost is a powerful Firefox extension designed to significantly increase audio volume across various platforms such as YouTube, Vimeo, and Dailymotion. It allows users to amplify sound levels up to 600%, making it ideal for those who require louder audio for better listening experiences. The extension features per-tab volume control, enabling users to adjust the audio independently for each tab, and offers fine-tuned volume adjustments ranging from 0% to 600%. The user-friendly interface ensures that even those with limited technical knowledge can navigate the settings with ease.

In addition to its volume-boosting capabilities, Boost includes customizable hotkeys for quick access to volume adjustments without disrupting the browsing experience. Users can decrease or increase volume by 10% with arrow keys, use the spacebar for a quick 100% boost, and mute or unmute sound with the 'M' key. The extension respects user privacy by operating entirely on the device without collecting personal data, providing a secure and private browsing experience.
