So, after i've played a game (from steam) i've opened firefox. But it ran slow. I opened task manager and surprise surprise 1GB of memory used in 7 instances of firefox. 7! Why that, i had just 1 tab open. not only FF but Chorme as well, 11 instances of it. Not to mention my pc restarted out of nowhere.

Is this a virus? It never happened before.

The new version of Firefox use multi-processes architecture, so what you are observing is totally normal.

More pages/extensions are opened/used, more processes are created.
