Your screenshot looks normal and the high CPU does not appear to be associated with a Firefox process.
You can visit about:processes in the address bar (Shift+Esc) to get more details about each process.
Reduce the number of processes per site by changing dom.ipc.processCount.webIsolated to 1 in about:config.
It is quite normal to see more Firefox processes running.
- process for the main Firefox thread (user interface)
- one or more content processes
you see more content processes when Fission is enabled - process for the compositor thread
- process for extensions
- process for WebRender when this feature is enabled
You can find the current multi-process state on the Troubleshooting Information page (about:support).

Multiprocess Windows and Fission Windows
"Remote Processes" (Web Content)
You can check the about:memory and about:processes pages for info about all processes. See also the about:unloads page for info about the tabs.
