Not the OP but for general browsing, I use them as a sort of append-only log. History can be good for trying to find something fairly recently, but my brain works in a manner where if I can remember the approximate timeline of something, I can usually find it if it was within the last 2-3 months just by scrolling through tabs.

After that I usually bookmark them all and nuke them.

Realistically, part of the idea is that if there's something of vague interest, I middle-click figuring I might revisit it at some point in the future. Usually this isn't the case, but as I know it'll wind up in my bookmarks at some point, there's still that possibility. Sometimes it even happens!

I do something similar to one of the siblings' replies with work though. One window per project/task with all associated tabs (e.g. documentation). Usually these don't get abused as much.
