The video doesn't load if you change volume.

The only one of those actually working reliably. Thank you for fixing the "original" one.

Вконтакте - не работает

Mostly does what it's supposed to, but unfortunately crashes some video players instead of boosting volume. Fine for YouTube use.

old and buggy interface, does not save position.
старый и глючный интерфейс, не сохраняет позицию.

Works on YouTube and other video streams just fine, but completely breaks on Bandcamp (including embeds). Really hope this gets ironed out soon, given that—salient privacy issues aside, of course—the previous app worked so well across the board.

Thank you for this, truly. Removing the ads/tracking from the original is good, making it open source is great.

Works great for me, better than the original without the deceit. Even get to pin it to the toolbar now. Thank you!

Does not work at all. Also it is the only add on/extension I've ever come across in over 20 years of using Firefox that will not pin to the toolbar.

works great when some youtube video has ultra low volume for some reason

Mozilla promoting spyware addons is bizarre.
Thanks for providing a clean one.

Needs a good update cause there are some issues still. When I change the value let's say to 140% and when I go back on it later it shows it being at 100% even though it still is at 140%. I've also noticed that it doesn't show the value while sliding which would be a nice QOL update.
