I used to be able to run Firefox without problems, but after updating to Monterey beta 8, I started getting pop-ups from MacOS telling me to force close programs. Firefox is using upwards of 30GBs of ram and swap on my 8GB M1 Macbook Air.

Measuring using about:memory spits out the following:

Main Process (pid 2140) Explicit Allocations

25,429.92 MB (100.0%) -- explicit ├──24,686.22 MB (97.08%) ── heap-unclassified ├─────472.45 MB (01.86%) -- heap-overhead │ ├──415.69 MB (01.63%) ── bookkeeping │ └───56.76 MB (00.22%) ++ (2 tiny) └─────271.25 MB (01.07%) ++ (31 tiny)

How do I limit the amount of RAM Firefox uses?
