Firefox using 50% + CPU when it is idle and stops when I close and reopen; then he resumes it after that that he is responsible for some time.

With Firefox loaded, but sitting idle for a period, he began to use 50% + CPU (by Windows Task Manager). This slows down everything even if nothing happens (openly) with Firefox. If I close and reopen, it's OK for a while, and then it starts again.

== In the last week, but I know of no specific case of ordinary use.
