Excessive RAM usage

Lately almost every time I use Firefox, RAM usage goes up to 5 GB, CPU usage goes to 100%, and my PC becomes unusable until I kill Firefox processes and wait 5 - 10 minutes for virtual RAM to be cleared out of disk and disk usage to return to normal. This is much worse since the last update, basically making Firefox unusable. Is anyone working on fixes so Firefox doesn't need 5 GB of RAM to open one simple web article?

Uncheck it, restart the browser and see how it goes. Just curious, but can you post the specs of you machine?
