Xfce Power Manger and watching movies full screen

[Georgios <gpdsbe+debian@mailbox.org>]

Hi there!

I'm running debian testing buster and I'm using xfce power manager.
In xfce power manager settings on "System" tab I activate "hibernate" on
30 minutes and on the "Display" tab "Put to sleep" after 9 minutes and
"Switch off after" 10 minutes.

When i watch videos on netflix (full screen) the display doesn't Switch
off in 10 minutes but the computer hibernate at 30 minutes.

I do not want my laptop to transits on hibernate if I'm watching videos
full screen.

I'm running debian buster with firefox-esr browser and xfce4.

Thanks in advance for your help.
