How it comes? Well, I just don't close them until I have decided whether I want to bookmark them. After month with a browser sessions quite some tabs pile up. (When it gets out of hands I bookmark whole windows… So there remains at least the theoretical possibility that I sort this out later. Even that happens only rarely.)
Before someone asks: From the technical standpoint it's quite easy to have so many open tabs. All you need is Firefox, Tree-Style-Tabs, and tab auto discard ("sleep"). It fits than in under 2.5 GB RAM even (which is less than Chrome with even a few tabs).
I have alone in this window here 4682 tabs open.
