I've observed that my Firefox frequently closes by itself, and I'm not sure what's causing this; does anyone know what's going on?

I'm on Ubuntu 22.04 right now.

Seems to be a memory issue. Your computer memory is being exhausted and this causes systemd-oomd.service to kill Firefox.

When you run journalctl | grep firefox | grep killed you may see an output similar to this

Checking on this link systemd-oomd.service could be the killer https://www.freedesktop.org/software/systemd/man/systemd-oomd.service.html

So the systemd-oomd.service is responsible for killing your Firefox process probably.

A solution would be to upgrade the RAM of your box.

PS, I experience similar behavior for other apps I use mostly such as Brave, Slack, Termius etc
