This is awesome! I didn't know i needed something like this for YouTube, but i did enjoy customizing the audio configs for whatever purposes at any given moment. I make the noise mumble-ey for when i go to bed for example.

breaks almost all video players

Does not work with enhanced tracking protection, on Waterfox atleast

Breaks 25% of sites. For example: https(colon)//watchflix(dot)bz(forward slash)watch(forward slash)tv(forward slash)4629(forward slash)season(forward slash)9(forward slash)episode(forward slash)7. You'll see.

Breaks audio for all clips on Twitch

Long-standing bug that messes with the headers of media HTTP responses renders this extension nearly unusable with the different sites it affects, including but not limited to Bandcamp streaming. Seems to be no intention of updating the extension--let alone fixing it--anytime soon either.

Doesn't work in Mozilla Firefox. You guys may need some better developers. It's been 2 months. There's probably a bug or bugs somewhere within the coding.

It does not work

Works fine on YouTube, but breaks playback on Bandcamp even when the EQ is turned off. Only disabling the extension helps.

This shit not even works anywhere!

ещё лучше было бы, если на каждую вкладку можно делать свои настройки звука. или же например на одной вкладке он работает (активирован) , но на другой вкладке он был бы отключен, до тех пор пока я сам не включу )

Legit just breaks the site i try use it on. Videos turn black and completely stop working. Deleted within 2min.

This extension caused a critical issue with video playback on certain websites that use CDNs and HTTP Range streaming. After installing it, videos would not load in Firefox in normal mode, showing the error “The media could not be loaded…”, while ads and other content played normally.

In DevTools, media requests returned status 206 (Partial Content), but were marked as “blocked”, indicating that the data stream was being interrupted on the client side. Interestingly, videos worked correctly in Firefox’s private mode, which made the issue harder to diagnose initially.

This behavior suggests that the extension interferes directly with the media playback pipeline (MediaElement/WebAudio), causing conflicts with browser security policies (CORS/ORB) or segmented streaming. After removing the extension, the problem was completely resolved without any changes to browser settings.

Use with caution, as this extension may break video playback on sites that rely on CDN-based streaming or cross-subdomain media delivery.

does not include a voice/speech/podcast equalizer set. no way to import equalizers nor sync them to my firefox account - so re-entering a preset visually on 5 firefoxes after each major firefox upgrade is not sustainable

Fine

funciona mal, se escucha más despacio con esto icluso subiendolo al máximo

I'm sorry but... it does not work.
I mean, the control panel is ok, but I have no effect on the audio.

Extra star for always being a reliable option.
