The real pain in the arse is relaunching each profile of mine.  I do so
manually, probably a jackass for not scripting something to do this, but
it's infrequent enough I just do it.  Nightly sort of thing would need
scripting and some restoration after.

I see merit in this, just wish these browsers would wipe their own arse
occasionally.

Yeah, I got a ventilation stand for my xps15, ripped it apart, installed
new thermal paste, thermal pads on mosfets to the chassis, and various
other thermal hacks as these are known to throttle down under load.
Thermals were better by a bit, but nothing astounding.  My office does get
hot with 2-3 49" tv's running all time, and various
network/security/wifi/other devices running in here a plenty.  Summer in AZ
is a challenge, winter I just use it as a heater for the house.  This is
excluding my server room downstairs that heats the bottom half.

My problem is the apps.  Obviously anything Microsoft is a browser pig, and
running 3-4 profiles with full email, calendar, teams, will use some ~500mb
of memory each, but by far no 40gb which is realized for use at the os
level, and not just reserved/virtual memory.  Gsuite isn't much better,
rest is just random crap.

I will check this out, I tend to live in text editors one way or another,
but never got used to using vim entirely in a shell.

Yes for most extents, I probably deal with 2-5 active projects each week,
random interjections for support, random sales calls, random requests for
info all over really.  I tend to just keep all the crap open all the time,
better or worse.

The one time I did, I found it quite foreign to me, and didn't like it at
all.

I'd probably still use kde4 if they ever fixed multi-monitor support, but
literally said "will not fix" and moved on to 5.x, where it took them a
good while to fix even there, and damn sure not fully.

Again, don't disagree I should do this more, but rather find some happy
place of memory to literally just keep it going as-is.

So with profiles, either firefox or chrome, it instantiates each
separately.  Meaning I install plugins, themes, bookmarks, everything
separately for each.  I presume things like cache as well, as that's where
things like M$ and even Google barf trying to share different accounts,
apps, and maintain separation.

I suspect this is why I find my browser using 40gb of ram, but really,
really!?

On my system with 128gb of ram, I'd find chrome using some 60gb of ram at
times.  Other stupid things like pavucontrol I'd find using 20gb of ram at
times.  As a volume control app.  It's always something.
