Power management
Firefox doesn't work with power management. It essentially turns the screen off and then sends the laptop to sleep when watching videos (in full screen). I have tried to disable hardware acceleration, but it didn't fix my problem. I am on 124.0.1 version - flatpack version on fedora, as the actual fedora version from "discover" app center cannot play videos at all. I am running on fedora 39, kde plasma, wayland.

Perhaps it's due to Screen Wake Lock API. Enter about:config in the address bar and switch dom.screenwakelock.enabled to true.
Video content should create inhibitors automatically without requiring the Screen Wake Lock API. Flatpak fullscreen video playback creates the necessary inhibitors for me on Ubuntu GNOME.

Fedora requires installing codecs, add the RPM Fusion repo then:
sudo dnf install ffmpeg
Flatpak also requires codecs for best results:
flatpak install org.freedesktop.Platform.ffmpeg-full//23.08

the flatpack you mentioned was already installed and the fedora version still turns my screen off.

I have turned that on, but it didn't fix my issue.
Does it still happen with the Mozilla build?

No, it doesn't happen with the Mozilla build. It isn't installable, isn't it? Is it just the executable?
