I think everyone is different, but for me bookmarks don't work (I just don't do it) and history rarely works (too much noise there).

Really, most of the time I can just close the tabs, and I will "re-discover" them when needed. But I don't do that: there is a fair amount of tabs that I don't dare closing because I feel like they contain something useful or I may need them.

I found an extension that I use as a "tab cemetery": a place where I can just store all the open tabs once in a while and start from fresh. And the two times a year I actually need to find one of them, I can open the cemetery and search there (it's organised by "dump date").

This extension is called "OneTab" (I have no interest in promoting it, that's just what I use). Works well for me.
