Hello, recently I noticed both of my computers get hot and fans get loud, I did some research and figured it's the Firefox that's causing it when I go to task manager the memory usage is always high and the CPU sometimes spikes up to 60-70% usage and the power usage is at very high . One of the laptops is windows 11 and the other is windows 10 . Please let me know if there's any fix to this. Thank you.
