After the most recent (or possibly the one before) Firefox update, when I am streaming radio via a radio player website, the stream keeps switching itself off after 10 minutes regardless of other activity on the machine. Apparently, this was reported a while ago (ca. 2020) but has only affected my experience per the above updates. Windows 10, latest Firefox version, e.g., url: https://siradio.si/val202/ but same behaviour with others sites.
