I replaced the cooling system of the computer...
When nothing runs in foreground the system under Linux is about 65° to 70° sometimes less, around 56°.
On windows 10, it's about 65° at minimum.
When I launch a firefox session either on Windows or Linux I got 85° to 95° of temperature /{
I first disabled the hardware acceleration but it seems it is necessary to help the system breathe.
I ran Firefox in debug mode many times without having clues help me consider I solved the issue.
I disabled the external components like plugins and options like pic to pic video control, ...
I went to about:performances but there is nothing there giving me clues to help me solve the issue.
