Which process specifically is using the CPU?
The process is firefox-esr
Does it happen if you use 115.6.0esr from upstream[1]?

Yes.
I also tried to downgrade to the previous version, but the problem is
still there.
It seems that the profile has been somehow damaged during the update
process.
I managed to use a backup to get the important files I needed and use
them into a newly created profile.
