i figured out why the youtube inside Whonix was not working because it was forbidden from working by noscript , so when i disabled the no script youtube worked.
the problem that this case is not similar for the other websites for example like vimeo, here is a pic showing that vimeo is working inside Tails but not inside Whonix:-

So it sounds like Whonix is fine (fast) and Tails is slow. Seems to be eligible to contact the Tails support if you care about this getting fixed.
yeah so true, browsing the tor browser inside whonix is way faster than tor browser inside tail or tor browser alone (inside windows). how can i report this test ? i mean how can i prove or show them that tor inside whonix is faster than the others ? is there commands or websites or …etc ? or i should film that as short video ?
