Was running the creators update fine with Firefox 56 only consuming around 300mb of ram and running smoothly. After the fall update it now runs like a cement mixer and consumes anywhere between 3.0gb and 5.0gb of ram when checked in task manager. Also seeing spikes in cpu usage along side the crazy ram usage.

Anyone else having experiencing this since the windows fall update ????
