Works well.
To the people having problems, if your extensions or browser(in my case librewolf) blocks WebGL it won't work. Simply enabling WebGL fixes the issue.

Works straight out of the box flawlessly. Nice to see that it's FOSS and I hope it stays that way.

Hats off to the dev for his work, you're awesome! Also, the fact it runs on a "visit" basis makes trusting it even easier. Didn't have to enable the optional option.

The extension works well...most of the time. Occasionally and at random, while active, the volume just boosts to what feels like a million percent, causes audio to be distorted and extremely and uncomfortably loud. After a few seconds it returns to normal. I lived up with it for a bit, I can't use it anymore.

Writes up and down for each tab

Hi Chaython, thanks for making an open source and slim volume control add-on. it is needed. i agree, the other one on Firefox is junk! i detest apps and etc. that harm us under the guise of offering something useful.

But i can't get it to work. On one site (movies7.to), it was useless. On another (archive.org), it muted the volume and i couldnt seem to re-tune it. i figure on another, it will also be a bother to rather than imrpovement of my experience...

I see that this is manifeset (aka "version?") 3. And that it is not necessary to give the permission for access to all websites' information?
what about the info on the single website upon which we apply the volume control add-on. could you provide a statement about what website info this extension searches for / analyzes, and how it uses this information? is it linked to our identities? could it be used for nefarious purposes if in the wrong hands? etc.
thanks again. i would ilke to use it.

It's stopped working completely. Makes no adjustments to volume and prevents any audio playing on several sites. Tried the permissions thing suggested in the latest change notes, but still won't work so I had to uninstall it.

EDIT: There is no visible means to reply directly. No sound on YouTube or Imgur. Only other plugins are Malwayre Bytes, Surfsharf VPN, LastPass and Gramerly.

Works well for sites it wont break

This extension does break bing for me and i found that out after enabling half of my extensions each time and narrowing down from there until i landed on this extension that was breaking bing

so i have to disable it when i want to use bing

Not working on the website I planned to use it for. Apparently it does work on YouTube but the audio there is mostly fine.

Overall the extension is really great, however it would be great if there were the ability to disable it for specific websites or for the extension to actually do nothing at +0 dB,

I am saying this, because currently there seems to be a bug with this extension that if you have it, and it has the permission "Access your data for all websites", videos in the online discord app do not make any sound.

I did check and without the extension or the permission that issue does not occur, however if i don't give the permission the teal dot of the extension requesting it is really annoying, so i think for now i will either remove it or simply disable it until and unless the issue gets resolved

(EDIT)
More specifically, video files in discord(at least ones with the .mov extension) don't make any sound, however everything else on discord still makes the sound with the extension active

When it's working, it does the job perfectly. However, it broke audio in some context. For example, I was listening to a podcast and if I try to listen to it from the website there's no sound, but if I access the file directly it works. But I really like the simplicity of the UI, it's exactly what I needed.

I'd like a feature to add a combination of "site domain+volume setting" to the addon.
So it automatically adjusts the volume down if I open this domain/any site on it.

Works as described. I'll never understand why certain sites (like Bandcamp or Patreon) don't have an on-site volume slider for their music widgets and instead just blast you at full volume... Being able to adjust the volume down per site/tab is just perfect and way better than having to temporarily turn down the volume for the whole browser instance. The FOSS nature and minimal permissions are the cherry on top that make this a perfect choice :)

the sound cut off this is not working

Best sound booster!

Get this extension! It is excellent! Here is why:
- works perfectly
- open source
- streamlined
- contains extensive documentation
- minimal permissions required to function
- the developer is very active (see other review for his/her responses and fixes)

There are many extensions that provide volume boosting functionality. The ones I have tried are completely untrustworthy. The main issues I have are things like: ad injection, NOT open source, pure copycats of other extensions, and so forth.

Pretty much the best Volume Controller in Firefox that I've found while also being pretty lightweight and straightforward.
