I've got ADHD and work hard to keep my tabs under control. As soon as they get too small to read (at least part of) the title, I lose the ability to keep track of what I've got open, so there's no value in keeping them open. That threshold is about 20 tabs per window, and at most about 4 windows, and ideally closer to 5 tabs each in 2 windows, when things are under control.
