User Agent: Mozilla/5.0 (X11; Linux x86_64; rv:69.0) Gecko/20100101 Firefox/69.0
Steps to reproduce:
I updated my Arch install with FF going from 69.0.1 to 69.0.2 when I recognized that FF used up 20% CPU. I've an eye on my CPU as I'm using 6 of my 8 cores for BOINC workloads which stop when the overall load exceeds 20%.
Actual results:
I restarted the browser and the machine but there was still a load without any page open, just an empty tab. When I start my other profile, the second instance uses 15 - 20% also.
Expected results:
No CPU load without anything open.

Just realized that the load isn't present when in safe mode. When about:performance isn't reporting anything, how to deduct which add-on is the culprit?

Your profiling results are not useful, they do not contain information about content/extension processes. Please run another profiling session and do not remove key information from the profiling results before generating a link to them.

Had to explicitly add those parts. I hope this contains the information you need. https://perfht.ml/2pOLz8D

When disabling the KeePassXC-Browser extension the load vanishes. I opened a bug report on their Github https://github.com/keepassxreboot/keepassxc-browser/issues/629
Sorry for the inconvenience. Please close the bug at your discretion.
