I've been banging my head against a wall trying to figure this one out. Every time a video plays on youtube, reddit, etc it will show normal colors for a split second then it will darken it and wash out the colors. Not sure what is causing this. Things I've tried: gfx.color_management.native_srgb to true in about:config Changing video settings in nvidia control panel Turning off hardware acceleration Restarting browser and PC Updating browser and video drivers, windows as well Turning off all extensions Trying with codecs both deactivated and reactivated No other browser does this and ALSO when I run firefox in private mode it doesn't happen and videos run normally. Also when I try to record or take a screenshot of it it looks normal. Thank you for any assistance.
