Ломает HEVC видео

The extension was fine until 2 days ago, it updated and now it has this weird ui that doesn't work well, it says 100% but when you toggle it down or up the volume changes and gets louder, like this new update broke everything, it was totally fine before.

was good up until yesterday with the new UI for it. cannot scroll down at all even though i see stuff further down, which id like to be able to access. the new design overall for 1.1 is just uselessly overdone, what was wrong with the sliders that made it nice and simple before?

Application works but messes up live TV streaming websites (somehow it blocks the live feed entirely and displays a black screen). Addon like "600% Volume" work better and don't mess up live TV on browser

Volume Master addon mutes the audio in latest Firefox instead of increasing the volume, therefore it's broken.
