Massive memory pressure issues

For reasons I have been unable to decipher, FirefoxCP Web Content is munching all the memory on my machine that it possibly can. I have gone through every about:config setting I am aware of or was able to find information about. Tabs should be unloading, memory settings should be deliberately restrictive, etc. However, my laptop is absolutely crushed by my browser.

I'm running the latest version of Firefox. I have UBlock Origin running but that shouldn't be this much of a lift. This is a 2020 MacBook Pro with an M1 chip and 16GB of RAM (I have no control over this. It's a work laptop. No, I can't just ask for a different laptop. Yes, I have tried.)

If anyone knows of tips or tricks I can use to hopefully restrict Firefox's memory usage ceiling, I'd be greatly obliged.

You can use "about:memory" to run a tool in Firefox to reduce memory use in a session. I'm not sure how helpful that will be.
Unfortunately the next best answer i can offer is probably "close tabs and use bookmarks" but I douht that is what you want.

Saving this thread, I hope you get some useful replies. I have a Windows machine with 16GB of RAM and Firefox is consistently sitting on about 15.6 of them. (Yes, I have horrible tab discipline lol)
- I do too but I feel there should be the ability to manage tab memory in a more intelligent manner than just "gobble gobble".
