For some reason does nothing.

using for firefox extension, where I needed an easy access Balance slider for right-left adjust. Sound Adjuster did nothing to vary the balance. I deleted it.

Not working on Firefox 128 "Installation aborted because the add-on appears to be corrupt." error

This often re-sets itself back to zero!

no effect

Doesn't work at all for me 😥

Good idea but doesn't work on most tabs. Even after refreshing the page, the add-on doesn't apply to the page.

Worked sometimes but has given up the ghost and virtually mutes the sound now.

didn't work whatsoever. changing volume would permanently mute whatever I was trying to adjust.

Doesn't work at all

Não funciona. Mexo o volume e não muda nada.

Doesn't work for Instagram. Just disables audio completely regardless of what values are set. Seems to be Instagram-related rather than this add-on as there are others with the same effect. Still - it means there are scenarios where this add-on is not fit for purpose.

Did not work. Too many bugs.

Does not work/can't get it to work.
