You can modify these prefs on the about:config page to disable the fade in and fade out. Leave out the quotes around the value (enter only two zeros separated by a space).

  • full-screen-api.transition-duration.enter: "0 0"
  • full-screen-api.transition-duration.leave: "0 0"

This may not work on Mac because Full Screen mode behaves differently.

it didn't really solve the problem, it help to not have anymore the black blank screen, but i got the half "frozen" second instead and the main tab is still automatically transferred to the right side

Anyway Thanks a lot for your tips i'll stay at "0 0" for the moment until i find a real solution Best Regards

Firefox might be adjusting the Tab bar automatically on a repaint as this also happens when you open a link in the background on a page when you have set not to move the focus to a newly opened tab and tabs are opened at the far right. Firefox would have to remember what tab is currently at the left end of the Tab bar and that isn't the case AFAIK, so Firefox focuses the current tab if more tabs are open than fit on the Tab bar.

OK, but why it never happen before i updated to the V42 ? i mean i am using FF from ... so long that i can't recall and it never happen.

Why it is behaving like that now ? and most important, it is behaving like that with me only or with everybody? because if we are just few to get this behavior, it mean that we got a glitch somewhere ... (i did re-install FF already, switch off the addons, etc ... to find out but nothing solve it)

This seems to happen with the HTML5 media player and not with the Shockwave Flash based player that Youtube may have used previously.

You can check that by trying between the Flash based player and the HTML5 media player.

You can use an extension to switch between the Flash player and the HTML5 media player on the YouTube website. YouTube Flash Video Player:
