I don't like it either, as my memory footprint grows exponentially with
each.  Office365/Teams is the goddamn devil here, as I tend to always work
for microsoft-y companies, and they simply do not work well if logged into
separate domains/orgs for me unless I keep them segregated to profiles in
either Chrome or Firefox.  This was a recommendation from gsuite support
when I first opened my business and had a hard time keeping things separate
even between personal and work.  Microshite's Teams app under linux hasn't
figured out how to log into multiple domains/orgs at once (ffs, just copy
Slack features), so I have to run them all in different browsers.

And yeah, a bit crazy probably, 3x 4k/60 displays (laptop built-in + 2x 4k
tv's via TB3 dock).  Before it was 6x 1080p's...  :)

I have this bit of an issue too with Teams.  Running each profile, I keep
firefox Task Manager pinned, and watch what are the worst offenders.  Worst
is always M$ teams using 300-400mb ram, O365 email/calendar second,
Hangouts, Gmail, Gcalendar a bit under, and rest get tab suspended
regularly.  Still somehow across numerous profiles, Firefox feels it needs
30-40gb of memory

Don't disagree here, but figure I'm not the only one working with large
text blobs either that this seems a nasty issue.  Maybe a better question
is if there is a better software.  Sadly there's no IDE's for dealing with
Cisco, Juniper, Arista, PAN, etc, so my life revolves around raw text at
times, and lots of it.

Just one Libreoffice with a lot of files.  Nice part is I can kill -9 it
and reopen right back to where I was at.   Again, multiple customers,
multiple docs, price lists from vendors, sometimes rather complex formulas
I use for configuration generation, Libreoffice does a _lot_ for me and how
I work, but hell, it tends to use less memory than my text editor even if
~4gb of ram.

Interesting note on baloo - every now and then it's gone mad for me and
I've killed it.  I know where my files are, I really don't need an idiot
search either.  Good point.

I used ubuntu for years, it wasn't much if any more memory friendly.  I
moved to arch trying to help that, but really about the same.  Not tried
gentoo in years, but suspect it's more usage than the distro hearing some
of the input.

AMD FX 3.8 GHz 4-core, 8G, no special handling of firefox.  However, I

So just some perspective, right now for apps::

Slack (logged into 6 different orgs), Telegram, Postman, and Signal all as
(slovenly) Electron apps.
Libreoffice with ~20 docs of varying complexity.
About 20 pluma text files of varying text sizes (30-50mb a piece on some,
yes big).
Two windoze vms, one linux network management server, a file harvesting
appliance of mine (weekend show time), and a tails vm.  ~20gb ram allocated
hard.
Few dolphin windows for file movement.
Pulseaudio Volume Control (which in itself has been notorious for memory
leaks).
Firefox, 5-6 profiles, half-dozen tabs at least, some far more.
Rhythmbox for music beats.
Fairly current KDE 5.19.5.

This gets a bit crazier during the week(s), but this is my staple, just
perhaps scales more horizontal than I probably should.

Really appreciate the feedback here all!
