This is not the first time this has happened although previously
when it started getting sluggish I killed all Firefox related

System logs show the start of the event.

No Swap. I prefer not on SSD

What type of content is generally being viewed/used in firefox?

When the system starts to become sluggish, have you looked at the
firefox 'Task Manager' under tools to see if anything stands out?
Previously I have seen the Isolated Web Co processes maxing CPU and
the CPU fans starting to roar. Nothing unusual in content at the
time and if I kill all ESR related processes it quiets down and I
can resume the closed windows and tabs at much reduced CPU
It's obvious the main culprit is Firefox-ESR and the Isolated Web Co
processes. What triggers it other than elapsed time I have no idea

I don't think it is actually a lack of memory. What I do see is all

Putting in swap may delay the time things start going awry but the
cause won't be lack of memory
I tried running a Debian desktop without swap and encountered the same
symptom -- crashed desktop and return to login screen. The solution was
two-fold:
1. Provision 1 GB of swap.
2. Add Xfce panel widgets so that I can see what is going on.
Between the two, I usually have enough time to kill problem apps before
a crash.
And, more memory would not hurt.
