Hello all! I just downloaded Firefox 42.0 and noticed a big issue with it on YouTube. Whenever I ask YouTube to go fullscreen, my whole screen goes black for about 10-15 seconds (audio still plays) and then the video shows up. Also, when I go back to the smaller view, it takes about 10-15 seconds for it to get out of fullscreen.

My computer is a Dell XPS 12 with 4GB of RAM and a Intel Core i5 4200U.

Anyway, thanks in advance! Please ask me ask many questions as you want. It helps us both.

You can try to disable hardware acceleration in Firefox.

  • Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"

You need to close and restart Firefox after toggling this setting.

You can check if there is an update for your graphics display driver and check for hardware acceleration related issues.

You can try to modify these prefs on the about:config page (leave out the quotes around the value):

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

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.

Thank you! It seems that changing the full screen api did the trick!
