When running the profile that doesn't play the videos, are you able to
see the videos choosing html5 from this link:
https://www.youtube.com/html5 ?

No! :(
Nevertheless, I did find the cause of the problem.
It was an addon that I rarely used. If I used it, I
used it in only one of the profiles. The add-on is
YouTube ALL HTML5 2.1.3
After I uninstalled it and restarted, then youtube
played normally. I removed it also from the 2nd profile.
Thanx.
