The actual link that states this is : https://plus.nhk.jp/info/faq/#C004-0002, where it states: Also, although we have not recommended watching on Firefox, the video will not be able to play after the update after May 23rd. Please use in the recommended environment.

@karlcow What do you think about this one?

This is just the FAQ. The real issue is at https://plus.nhk.jp/ with https://plus.nhk.jp/info/faq/#C004-0002

It seems that NHK is making a conscious decision to drop Firefox. The issue is more understanding why.

From today, NHK+ seems not to support Firefox. Even if changing to Chrome UA, video streaming isn't started. Although they seems to use MPEG-DASH, Firefox doesn't recognize this stream even if it is downloading *.m4s.
