Fixed in the version 1.0.4 for the site https://news.v.daum.net . But unfortunately sound can't be controlled by the add-on as the video server cdn.videofarm.daum.net does not return the header Access-Control-Allow-Origin.
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.
