I updated firefox today and immediately saw 30% CPU utilization with two youtube tabs open. It's annoying AF.
Anyone else experiencing the same?

Not here. Same version under flatpack on bazzite, works fine with many tabs open and one tab watching videos. As an experiment try starting in safe mode to see if the behavior changes.
firefox -safe-mode
flatpak run org.mozilla.firefox --safe-mode
# or hold shift whilst launching

Same here, Firefox 147.0.2, macOS 15, Apple Silicon. "Firefox GPU Helper" keeps using 30-40% of a CPU core.
I think it's not strictly connected to using YouTube in my case.
