Thanks for reading through this. No Nvidia card. it's AMD Ryzen 7 CPU with integrated Radeon Vega 10 GPU. 20 GB system memory with 2 GB allocated for the video card. I didn't install anything for graphics, I just let Fedora do its defaults.

I looked up the codecs to get the specifics. This was the first thing I found when having Firefox + YouTube issues: https://docs.fedoraproject.org/en-US/quick-docs/openh264/

Installed that and it wasn't any better. Then had to figure out how to remove it and try the rpmfusion stuff (whatever that is).

Here's the output of systemd-analyze critical-chain:

The time when unit became active or started is printed after the "@" character.
The time the unit took to start is printed after the "+" character.
