Does this happen for other anons?
YouTube videos, opened in another tab, take about 90 seconds to fully load. It starts out looking like picrel1 after about 1 or 2 seconds, then stays like that for a minute and a half or so before showing the "normal" display, picrel2.
Maybe anon has a plugin that's causing this? Haven't debugged, yet, just noticing so far.
Anon suspects YouTube added code to force this delay, just as they added code to show a "don't use ad blockers" notice several weeks ago.
Appreciate any feedback, thanks.
