Public bug reported: Firefox is currently eating 100% CPU (firefox was nearly unusable, confirmed with htop), however the gnome system monitor reports 0.99%.
This does not appear to be a simple multiplication error since a single process called Isolated Web Co is reported as much higher at 6.31 percent. See the attached picture which displays process htop alongside gnome system monitor.
