⁉️Dear user, please note:
A few videos may become silent after using the addon due to the error: "The HTMLMediaElement passed to createMediaElementSource has a cross-origin resource, the node will output silence." Unfortunately, we haven't been able to resolve this issue for years.😟It might be a Firefox bug.
Please be patient.🙏Reload the page with the video, and it should play again.
