The plugin works very well at what its supposed to do, but unfortunately it has a major side affect.
It prevents video thumbnails from previewing videos across all sites and even prevents videos from playing on some sites.
So even though its a good equalizer its unusable because of its major side affect.

The only EQ that works for me, and it does a good job.

VERY GOOD EQUALIZER
Thanks, Muyor!

Add-on brake video playback like streamable and can't load messenger properly, after uninstall everything start working normally

Good addon. But it has one critical bug which destroys all advantages of this addon for me.
It breaks the speed control for playback on all sites.

This equalizer is really great. It's easy and makes a big difference in sound quality. For some reason it breaks CBS all access (cbs.com) which is regrettable. Just turning off the equalizer doesn't solve the issue, it has to be disabled or removed.

Interferes with video playback speed on any video (youtube/twitch/etc.)

i didint find anithing better than this......firefox update ur extention option\
