Firefox using HUGE amounts of CPU and memory

more options

I'm using the latest Firefox on Win10, with a fairly powerful laptop (64 gb RAM, intel i7 2.3 GHz chip), and for about a month now, whenever I use it, it uses so much CPU all the time that my laptop is overheating (slight hyperbole, but it's definitely churning the fans a lot, and the area around the keyboard gets hot to the touch). Sometimes it uses up to 45% CPU, and over 20% memory!!! (as reported in the task manager) Usually around 20-25% though. While Chrome, at the same time, is using 0.1%. It's not just when starting up, either, it's continuous during use, until I quit Firefox.

What the h*** is going on?!? I've tried the troubleshooting steps, but it remains crazy regardless of turning off extensions, and I'm just using the default theme. I notice it's mainly when loading images, like on social media.

This is insane. What is happening. Can someone help me?

What gen i7? How many windows do you have open and how many tabs in each window? As a test I would suggest you open the same amount of windows and tabs with the same content in any other browser and compare.

It's Intel 11th gen i7. It happens even if I only have one window open, if that window is on SoMe (several different sites). I don't really use tabs that much, and it happens even if there are none open. As I mentioned, I opened Chrome and got a vastly different result - only 0.1% CPU usage, which I think is reasonable if you're just looking at non-GIF memes (or even gifs, but DEFINITELY when just viewing jpgs or whatever).

I also noticed that it seems to crash explorer.exe sometimes, though I don't see it under crash reports. Nothing else I run does this.
