Task manager now shows 4 instances of Firefox instead of 1. I just upgraded to Firefox Quantum 57.0, but it was like this before the upgrade. Is this something new, and OK?

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
