I encounter a bug, which youtube website still loads normally. The problem occur when I tried to open one of the youtube video and it just a black box with no normally youtube playback button, but the recommendation can be view as I scroll further down. Entering in-video mode, cause it to going back previous page but no small video playback at the corner. Normally, I would think my internet was a bit slower, but opening youtube in chrome or other browsing software have no such problem. I try watching Netflix on firefox, and it just works fine but the youtube things still occur. Thank you.
