Best Volume Booster Extensions for Chrome & Firefox
If you’ve ever watched a YouTube video or streamed music online and thought, “Why is this so quiet?”, you’re not alone. Browser volume limits can be frustrating, especially when your speakers are working properly, but the audio from certain tabs remains weak. Luckily, there are powerful browser extensions that can boost your sound instantly without extra software. Let’s look at some of the best volume booster extensions for Chrome and Firefox that actually work in 2025.
1. Volume Master
Available for: Chrome
Why it’s great: Volume Master remains the most popular audio booster for Chrome, and for good reason. It lets you raise the volume of any tab up to 600%. The clean, minimal interface makes it easy to control sound on a per-tab basis, meaning you can keep one tab loud and another quiet. It’s lightweight, free, and doesn’t require any login or permissions that feel invasive.
Pros:
- Boosts volume up to 600%
- Easy to use
- Works smoothly with YouTube, Netflix, and Spotify Web
Cons:
- Chrome only (no official Firefox version yet)

2. Sound Booster
Available for: Chrome & Firefox
Sound Booster is one of the newer players, but it’s quickly getting attention. It works similarly to Volume Master but adds an optional equalizer, giving you a little more control over bass and clarity. It’s perfect for people who want louder audio but also want to fine-tune their sound quality.
Pros:
- Works on both browsers
- Built-in equalizer
- Simple, responsive design
Cons:
- May cause minor distortion above 400% boost

3. Audio Equalizer
Available for: Chrome
Audio Equalizer isn’t just a volume booster; it gives you complete control of your sound. You can tweak treble, bass, and mid-tones using preset profiles like “Pop,” “Jazz,” or “Rock.” If you’re a music lover, this one is worth trying. While it doesn’t raise the volume as dramatically as Volume Master, the audio quality stays clean and balanced.
Pros:
- Great sound control
- Custom EQ presets
- No noticeable lag
Cons:
- Doesn’t boost beyond 200%
- Only available for Chrome

4. Volume Booster Plus
Available for: Chrome
If you want a simple, one-click solution, Volume Booster Plus is another reliable option. It works great for watching movies or online meetings when your laptop speakers just aren’t loud enough. Its main strength is stability; it rarely crashes or distorts, even when you push it hard.
Pros:
- Fast and easy interface
- Reliable sound boost
- Free to use
