I think it comes down to differences in how our minds work. Some require neatly organized desks while others thrive on what to others looks like a chaotic, scattered mess of unrelated documents. It's kind of hierarchal vs. spatial, and it's also one of the key differing principles between Windows-style and Mac-style desktop environments.

I have 10 windows open and 8 of them have about 20-30 tabs (two of them have less than 10 each), I don't think my hoarding is thriving. It's more of a scatterbrain saying "Oh I'll get back to that idea", and taking days or weeks to get back to it.

In Vivaldi, vertical tabs mean each tab takes about 40 vertical pixels of height, and about 250 pixels width, so I can skim through the titles of each tab...

> severly degradated performance

I have 546 tabs in Firefox (on macOS) at the moment. I've never noticed any degraded performance. On my phone (iPhone) it's 490+ but that's because 500 is the max. I don't think it keeps them truly loaded until you go back to them.

That is the way I work.

Now my bookmark list is crazy. I have started using 'open all' and then reviewing items in each folder to see if they are worth keeping. 99% of the time. no. Many times they are from years ago and the site doesnt even exist anymore. I have some items in my folders that go back to 1992. I have a bad habit of 'oh that is mildly interesting ctrl-d time'. Usually a few weeks later 'what was I thinking'.

My tabs however are wildly focused on what I am doing right now. Once that task is done. I close them out. Think my max is 20 tabs. But usually I really only need about 5. The rest I close out. I probably can find it again with search. That is how I found it the first time...

That also reminds me, time to delete more folders.

Ditto on the working set. For the 'crazy' bookmark lists: I now have 220 bookmarks, max 4 levels deep, counting the bookmark bar as level 1. And that's work and private combined. Before I add a tab to the bookmarks, I ask myself: Am I likely to need this again? If the answer is not a full yes, I just close the tab. It can also be found again quickly enough with a simple google search or the browsing history.
