I use the profile manager and have dedicated (and isolated) profiles for some sticky web apps that I need to keep open through a work shift, e.g. Slack and G-Suite. My G-Suite one might even have a dozen tabs that I'll have it keep and restore on restart, holding documents that are part of a weeks or months long project. The Slack one would just be one tab per Slack org at the times when I've had to juggle a few, as I found that easier than using the Slack UI's internal way of switching orgs.

I guess it's my old school way to have isolated containers for these 1st party sites I am forced to use. I'll even cut and paste 3rd party URLs from those back into a general profile, rather than browse off to other content from those "apps".

In the general browsing profile, I don't really leave anything logged in or open in tabs for more than an hour or two, often much less. When I get up to take a break, I generally have exited the browser too. So, I may close it tens of times per day, and have it set to clear history and cookies on exit.

It's partly my defiant personality wanting to throw a monkeywrench into the tracking and personalization miasma. But it is also just more comfortable for my mind to be coming back to a cleanly reset workspace than some sedimentary remains of the past.
