I used to be like that - but I use 2 profiles in Chrome, 2 profiles in Edge, and 1 profile each in Firefox and Firefox Nightly (my actual go to browser for a variety of reasons).
My Firefox Nightly also has the addon Tab Groups, which is a revival of the old Panorama mode, because I use it extensively - as in I use TF out of it. Firefox Nightly alone has 120 tabs open at any given moment, split into 12 different groups. Now, you might think “OMG, that Memory!” - but nope - With Tab Groups only the tabs I’ve opened and actually looked at take up RAM, the rest are there but not ‘active’ per se. And with it being Nightly, well, let’s just say it updates at least once a day, usually 3-4 times a day - and when you restart the browser, all tabs are back in their inactive state until I open them. The grouping is beneficial because I never have more than about 15 tabs on display at any given time.
I use Tab Groups in regular Firefox (stable) also, but only have 81 there.
But Chrome is not so nice. I recently had about 20 tabs open and it was murder - of course, some of those tabs were stuff I use regularly, like various GMail and G-Suite email accounts, Twitter, the MSI website, and numerous other places, including Eve community, but after cleanly installing Windows last weekend, I decided to try individual apps for some of the sites I visit regularly on my system, having dedicated apps that I can open as I please. I did this with GMail For Desktop, the Windows Store apps for Facebook, Twitter and Reddit. and now Eve Community via the above method. Chrome is now pretty with fewer tabs, and I can make a few more of those into PWAs easily, as well. Like the Android Developers sites,
It’s a lot easier than opening tabs from bookmarks and closing them out when I’m done - because 1 browser with multiple logins for the same site gets to be a PITA to manage.
