Limit Memory Usage using cgroups

Example: firefox

Limiting memory per process with cgroups

cgroups (abbreviated from control groups) is a Linux kernel feature that limits, accounts for, and isolates the resource usage (CPU, memory, disk I/O, network, etc.) of a collection of processes. You can use it to make sure specific processes and their children cannot allocate more than a given amount of RAM.

On Ubuntu you must install the following package:

Instructions

Location: File > Preferences > User Snippets > python.json
Location on disk: ~/.config/Code/User/snippets/
Copy Line 15 to 30 and paste in python.json if it exists, else create and copy entire contents.
