Be sure to follow the rule before you head out.
Rule: You must post before you leave.
The issue is that browsers don't release much memory back to the system when it's needed. I wish they'd work more like the Linux kernel's VFS caching later, but they don't (and might not be able to. For example, I do don't think the Linux kernel has good APIs for such a use case).
You can write limits to and then poll files in
/proc/pressure/
to be notified of resource pressure. Systemd will also set an environment variable for similar files for your cgroup.
