Windows 10 How to manage browsers processing in Windows 10?

[GNS]

Hi,

I opened three browsers; Firefox, Chrome & Opera in Windows 10.

I didn’t open any website in any browsers.

However, I see browsers are utilizing more process.

Can I control it?

If yes, let me know, how to manage browsers processing so that it doesn’t utilize more processing in idle mode?
