I was very excited about this improvement (it was covered on phoronix IIRC), but my systems still ends up thrashing when Firefox grows too big, unfortunately.

I usually keep an eye on the memory usage I have displayed in the taskbar, and have sysrq activated in case. I tried multiple things, including avoiding swapping to disk (only using zram), and Zen kernels. I'll have to see if I use MGLRU.

Do you use a userspace OOM killer, like oomd or systemd-oomd?

I haven't set that up yet, though I've watched the recemt developments with interest. Another option would be to launch everything (or just Firefox) in cgroups.
