I was typing in Word and noticed that the keystrokes were lagging. I checked Task Manager and found that I had 84% memory usage, over 600 MB, almost 12% due to FFox. I closed it and reopened it and same thing. I had only 1 tab open, Google News. I tried Chrome and it only used 175 MB and Edge about 300 MB. Furthermore, that single page caused 13 instances of FFox in Task Manager. Why is FFox such a memory hog?

I have a Surface GO with 8MB RAM and a 256 GB SSD that is 60% full running Win 10 Pro 22H2.
