I have several chrome windows open at a time and all the google chrome helper processes are using too much memory. How can I disable these from starting? All the instructions I’ve found seem to be for older versions of chrome.

At that time Google released Chrome version 74.0.3729.169 to fix Chrome helper high CPU and memory usage problem. After a long forum discussion, the problem still persists in 2020.
