Not a replicant

You, too?

It’s true. There’s a lot of special issues that fin their way into circulation.

Firefox on my raspberry pi grinds the thing to a halt, so I created a shortcut:

systemd-run --scope -p MemoryLimit=500M -p CPUQuota=50% firefox-esr

You say it doesn’t top out on memory, so you don’t need the -p MemoryLimit=500M parameter. Set your compiler CPUQuota to maybe 80%, or whatever you can work out with trial and error.
