OOM killer should target "Isolated Web Co" before "firefox-bin".

[HT-7]

From dmesg: Out of memory: Killed process 618748 (firefox-bin).

In earlier versions of Linux Mint such as 18, the OOM killer (out-of-memory task killer) first targeted the sub-processes of Firefox, such as "Web Content" (I don't even think "Isolated Web Co" existed a few years ago).

Now, however, it takes down all of Firefox.

Please revert back to the correct and less desctructive behaviour of Linux Mint 18. Thank you.

Found a solution!

Run as root:

echo -17 > /proc/$(pgrep firefox-bin)/oom_adj

I am surprised this is not more widely known.
