Good job , increase volume

It is working great, but I am not able to use it when I am manipulating the playback speed of video in YouTube, so if you are like me who often manipulates the playback speed then this extension is not for you, or else I would request the devs to see into this and resolve this bug or whatever issue it is in the upcoming update, apart from this the extension is seemless and no issues faced as of now.

Does what you want it to. Small bug though. Twitch clips are broken when this extension is enabled. Could you please fix whatever the issue is, or add a feature to disable the extension for X domain.

Good job

Great add-on. Some films on streaming format were just too low volume to watch on my laptop. 600% Sound Volume was a game changer and made streaming videos a real pleasure.

This is definitely the only such add-on that does what I want it to do. Thank you, Aliaksandr!

I love this and it works nice! One minor problem though: on Youtube, when I use it, videos will only play on 1x speed, neither faster nor slower work anymore. (2021) ... Three years later (2024), I still use it on a daily. Greatly recommended.

Great! Just great!

Все отлично, но на некоторых сайтах вызывает ошибку «Html5 video file not found», пришлось отказаться от этого дополнения.

Everything is great, but on some sites it causes the error "Html5 video file not found", I had to abandon this addon. = (

Suddenly this extension is causing cross-site origin issues. Sketchy.

best volume booster out there , used something on every browser , but the combined force of firefox and you made it good , before I had to plug in so that the audio does not distort , but here it's perfect either way

Even though it works very well, somehow it causes error #4000 on twitch. Bummer

Breaks twitch videos and I am unable to change playback speed while this is enabled. Otherwise, it is a great extension that has helped out a lot.
