I can finally hear youtube videos that are too quiet because the uploader failed to test the audio levels before uploading.

Broke video with error "firefox The media could not be loaded, either because the server or network failed or because the format is not supported"

works without conflict like some others, but i wish we could dial in the volume more and not just 10% increments.

600% but only works until 200%. Misleading

NOT WORK!

Can you Add a shortcut to enable and disable the increase.
i need to disable and enable it everytime a video changes in drm based site.
