settings for stream isolation for JDownloader ?

*JDownloader can’t make me uniquely identifiable to the website so much as adobe flash on TBB from one hand because of fingerprint protection that serves TBB and even if i set JDownloader for isolation. On the other hand , adobe flash is so bad for privacy technically so if enable it on TBB whonix transform the anonymity of TBB to pseudoanonymity.
*Are more users that use adobe flash TBB whonix than JDownloader isolated whonix because the last is less documented ,less known , need more configuration .
*Chrome have not fingerprint protection like TBB.
*i am pseudonymous when use adobe flash on TBB whonix , so there is no way to be true anonymous when watch flash videos online or download them . 'That i understand until now, confirm that please.
