FF slowing my online activity

Why does FF show 5 windows in the Task Manager when I have only one FF window/tab open? FF is using 50% (one gig+) of memory even though there is only one FF window/tab open. This is slowing my computers online activity—sometimes greatly. Is there a way to fix this, other than not using FF?

I am using FF 84.0.2 (64-bit) with a 64-bit PC. All critical and security updates are up to date and the machine seems to be free of any malware.

Thank you for your help.

More than one process is normal for the current Firefox. http://www.ghacks.net/2016/07/22/multi-process-firefox/

Multi-process Firefox is codenamed "e10s". https://wiki.mozilla.org/Firefox/multiprocess
