Works, and autostarts after browser restart. I don't know how you guys cannot make it to work.

muy eficiente, y especifico, es genial.

Эквалайзер плохой

works perfectly with Deezer!

Best audio equalizer out there! Especially if you are looking for extreme bass settings when you listening to songs :D

I was hoping to find this useful. but it straight up made bandcamp not work. which was disappointing

Хорошо работает в Хроме и Мозилле на Windows и Linux.

I recently replaced a pair of speakers that was at least 20 years old and were now noisy. I replaced them with a pair of cheap speakers (Insigna, a Best Buy brand). They work pretty well, but I noticed the sounds of voices weren't too clear.

I decided to search for a graphic equalizer that would work with Firefox. That's when I found Audio Equalizer. I've only been playing around with AE for a few hours, but I am really impressed! These cheap speakers don't sound so cheap anymore!

This extension has a nice selection of presets to try out. You can customize your own settings too. You can optimize for music or speech. Now my desktop PC sounds better than my TV!

This is a really cool extension. Thank you Muyor!

Would love to have the option to enable the addon only on specific sites - whitelist/blacklist sites.

This add-on (Audio Equalizer) prevents playback of any video thumbnail that doesn't have audio especially in less popular websites. This can be easily ascertained by simply disabling the add-on (Audio Equalizer) and seeing the problem disappear.

While in private mode with nothing but this add-on (Audio Equalizer) enabled and after the page is fully loaded. Bringing the cursor/touch pointer to a standstill over an 'image' thumbnail will trigger the fetching and playback of 'video' thumbnail.

Afterwards in the developer console (F12) we see the following warning (Yellow Background) generated immediately:

----------
An AudioContext was prevented from starting automatically. It must be created or resumed after a user gesture on the page.
----------

I would like to point out that I have had already changed the Autoplay permission in Firefox's privacy setting page (about:preferences#privacy) for all websites from 'Block Audio' to 'Allow Audio and Video' Before Installing this add-on (Audio Equalizer).

Above warning is then immediately followed by the error (Red Background) below:

----------
Uncaught (in promise) DOMException: The fetching process for the media resource was aborted by the user agent at the user's request. inject.js:97

I tried to use the ON/OFF button in the add-on (Audio Equalizer) from its own popup so that the add-on (Audio Equalizer) remains enabled in Firefox but doesn't try to inject the following script which is the source of error ( into the page:

moz-extension://[ADDON-UUID]/data/content_script/page_context/inject.js

However probably thanks to Audio Equalizer's 'Access your data for all websites' permission, Unless you disable the add-on (Audio Equalizer) from inside the Firefox's add-on page (about:addons) the script will still get injected and thus no video thumbnail playback.

I even tried adding 'moz-extension://[ADDON-UUID]' to uBlock Origin's "My filters" and "My rules" tabs based on each tab's correct syntax while removing 'moz-extension-scheme' from "Trusted sites", nevertheless Firefox would still inject the script into the website so long as the add-on was enabled despite "ON/OFF" button being gray (presumably indicating an 'off' state) rather than black (presumably indicating an 'on' state) according to its own popup menu.

As it's not properly programmed to handle audio-less videos and there is no way included to prevent itself from activating on user-defined specified websites (say by actually having an options tab that comes with a configurable exclusion list inside add-on's Firefox page rather than its popup with its ineffective "ON/OFF" button); I believe that the badge granted to this add-on by Mozilla Foundation is without merit and should be revoked.

After all the following is a direct quote from hovering over the badge of each add-on recommended by Mozilla Foundation:
"Firefox only recommends extensions that meet our standards for security and performance"
