i have a problem with firefox. when i am using firefox and youtube the fan of my MacBook pro (2021, intel i5 2.0 GHz) turining higher and higher.
e.g Video (1080p or 4k).
with Safari i have 62°C CPU and GPU temperatur, FAN-Speed 1000 - 1500rpm, GPU (100-200MHz)
with FireFox i have ca. 100°C, FAN-Speed 4000-5000rpm, GPU (600 - 950 MHz)
FireFox Version: 108.0.2 (64-Bit)
MACOS: 13.1 Ventura
Is this a bug on firefox, or why firefox need so much more ressources from CPU and GPU by using youtube copared to safary ?
