Работает, не идеально, но хотя бы так, это единственное рабочее расширение Эквалайзер для FF, надо только добавить Preamp

Good but does not allow videos to play in youtube studio when showing analytics.

the equalizer works... the audio sounds better. great !

음질이 향상된다는 장점이 있지만 특정 사이트들마다 게시글에 올려진 영상들이 재생이 자주 안되기도 해서 큰 단점이 있어요.(특히 구글맵의 영상들)
개선 바랍니다.
Although it has the advantage of improving sound quality, it has a major disadvantage in that videos posted on certain sites often do not play (especially videos on Google Maps).
Hope for improvement.

This works great, but for some reason breaks Musescore.com, even when turned off.

En simpel brugerflade de fleste kan finde ud af. Kunne godt bruge flere "Soft" Presets, men det kan ske i fremtiden, at det kommer.

Hello,
a useful add-on that significantly improves the sound, no matter what sound device you use.
Thank you for that.
Unfortunately it doesn't work as hoped on a website I use often. The sound is switched off completely.
Even with the equalizer deactivated there is no sound:

I would be very grateful for a short explanation.
Best regards
Edit:
Hello again, I was able to solve my problem myself. Simply add the website to the whitelist in the Firefox context menu. 👌
Thanks again

good extension. unfortunately though, it stopped rumble.com's videos to work properly. they can't be played with this extension on/active.

Works great when it works.
But for sites it doesn't work on i need to disable the extension for me to view the content, so I would really like a whitelist/blacklist for the extension to stop working on certain sites

works a treat when it works.... some sites are broken where videos wont even load, and some gifs wont autoplay. took me a while to figure out it was this addon. turning it off and on in the addon itself wont work, has to be enabled and disabled via firefox. best example i have is steam.com and discord.com. works fine on youtube and others tho.. ill keep using it for now, and turning it off and on accordingly. shame for the inconvenience, cuz it really does work a treat when it works..

¡Extraordinario... es como el ecualizador de VLC, se puede personalizar y guardar una variante! PERO YA NO SIRVE en vk ni en ok.ru ¿por qué si antes iba de maravilla?

Works great for HTML5 video/audio streaming, but won't work for certain formats. Off the top of my head, it doesn't work with Amazon Prime Video for example.

Pretty good nonetheless, light-weight and unintrusive.

Overall, I am satisfied with this extension. However, with this extension installed, I am unable to play videos on Google Drive. Disabling all extensions will allow playback, and enabling only this extension will prevent playback. I would be satisfied if this issue is fixed.
