Firefox Equalizer: Add an Audio Equalizer to Firefox, Chrome and Brave
A free equalizer for Firefox is the Audio Equalizer extension (by Muyor), which adds a toolbar equalizer with presets to the browser. In Chromium browsers such as Chrome and Brave, you install equalizer extensions from the Chrome Web Store the same way as any other extension. Settings apply to all sites, and you can save presets for different audio types.
This page explains how to add an audio equalizer to your browser, what the extension can and cannot do, and what to check before installing.
How do you add an equalizer to Firefox?
Install Audio Equalizer from Mozilla's add-ons site and pin its icon to the toolbar. On Firefox, the Audio Equalizer add-on by Muyor currently has about 52,000 users and a 4 out of 5 rating from 691 reviews. Its listing says it does not collect data. A click on the toolbar icon displays the equalizer.
An alternative is Audio Equalizer and Amplifier by Lunu, which offers 10 frequency bands from 60 Hz to 16 kHz, about 12 presets, profiles and a pre-amp. It has far fewer users (about 2,500) and a 3.2 rating, so read recent reviews first.
How do you add an equalizer to Chrome and Brave?
Brave supports the Chrome Web Store, so you add an equalizer to Brave exactly as you do in Chrome: open the extension's store page and click "Add to Brave" or "Add to Chrome", then review the permissions. Audio Equalizer is available for Chrome, Brave, Opera and other Chromium-based browsers. In the original 2020 test on this site, installation in Chrome went through without any issues.
The extension needs the "access all websites" permission because it runs on every site rather than a selection. In Chrome the icon may sit in the Extensions menu, so pin it to the toolbar for quick access. In Brave, manage it from Menu, More Tools, Extensions.
What can the Audio Equalizer extension do?
Audio Equalizer lets you adjust frequency sliders in the popup, and changes take effect immediately. Changes apply globally, not per site or page. Some commenters reported that it did not always work and fixed this by reloading the page.
To work around the global setting, use presets. Its Mozilla listing mentions built-in presets such as pop, club, party and soft rock dance, and you can save and load your own. It also has an on/off toggle, a reset button that returns all frequencies to the default, and a mono option for users with hearing problems.
Is Audio Equalizer safe?
In the original 2020 test on this site, the extension changed the audio output on the fly while videos were playing on various sites. Any equalizer extension that reads all websites deserves a permission check: confirm the developer, user count, recent updates and privacy statement on the store page before installing. Automatic per-site presets would make it more comfortable, but the extension applies one setting globally.
Chrome users may check out Audio Channel for a similar extension. Windows users annoyed by different playback volumes may want to check out Wale instead.

I have tried it in the past, but as many are reporting on the feedback page it is sorely buggy and interfering, it’s also veeery process hungry making playback on youtube very choppy, this extension shouldn’t even have been suggested as it’s too immature and may have security issues too.

It’s much better to install an equalizer directly in the OS, Linux has PulseEffects which has all kinds of audio manipulation features, for Windows one could try for instance Equalizer APO.
This looks good, and I’ll have to look at the Audio Channel extension, too. Thanks.
Nope–different developer. The extension I use in Chrome is by DevAudio.
The extension reviewed here is my Muyor.
I’ll have to try them both, I guess.
The volume on FF when streaming was so low all of the time, I only stream with Chrome and the extension by DevAudio. Not sure why that is.
Funny, I’ve been using Audio Equalizer on Chrome for years because of Volume Issues when listening to various streaming sites.
Glad to know AE works with FF now–at the time, it didn’t.
It’s useful for me.
My laptop came with Dolby Home Theater preinstalled which includes an equalizer option. I’ve experimented with it in the past, but haven’t used it much recently. Here’s what it looks like: https://imgbox.com/oC7U1uFE
This extension breaks playing videos on sites, having more than one playable. Just to mention, because some people might wonder why.
Whilst working fine on Youtube, Dailymotion, etc. it breaks the start of videos on sites like 9GAG.
So @Claymore, the more you use this extension, does this breakup the sound with more “frequency”? :p
(I’ll show myself out)
