WOOOOOW working great, thanks

Worked great on all other sites except on Twitch were when watching clips I kept getting error 4000 and was unable to view them. Tried removing browser cache, checked audio drivers that they were correct and auto play feature which was correctly allowing all audio and video. Those might have been the problem according to guides to fix error 4000. After trying those it still didn't work so tried disabling add-ons and after disabling your add-on it started to work again. What might have been the cause I have no idea so I decided to forward this problem to you so I don't have keep disabling and enabling your add-on over and over again. Using Firefox version 76.0.1.

good

god tier dude, you're the mvp for making this it's so useful

firefoxでamazon videoと読売TVのオンデマンドを見ていると、台詞が聞き取れないくらい小さかった。PCのスピーカー設定を大きくするとある程度改善はされますが、それだと通常の音が大きすぎて困る。
firefoxになにか原因があるのだろうと思って調べましたが、解決策が見つかりません。
そんなときこのアドオンを見つけました。
600％なんて書いてあるので、いきなり600％まで大きくするのかと思いましたが、細かく10％単位で、しかもタブ毎に音量を変えられるのでとても使えます。

If you install this add-on, videos from some sites cannot be played. for example, https://news.v.daum.net/v/20200512193407055

does what it claims. i love it!

have to set it for every single video every time. I didn't even reload/refresh the browser or went into another page. if it could remember the volume level for a page at the very least before I close the tab or reloaded it.
