Good day, I have since like more than half a year the issue that during Video playback with Firefox (no matter if private browsing or not) the screen standby time from My Debian 12 with Mate Desktop OS is functional, but it wasn't the case in past mid-term (also other website Video playback trigger that setting, while for example VLC keeps the screen alive, although the setting isn't changed). Why does Firefox no longer surpress the energy saving option of the screen standby time; does Debian 12 (Mate Desktop) have a change or something else? Thanks in advance!
