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?

What do you have set here?

This page needs to be updated because the option to change the Content process limit without going into about:config(dom.ipc.processCount) is gone in 89.  ;-/

The default, Use Recommended Performance Settings is checked.

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