Tabs-outliner helps me zoom out and see the forest of currently opened tabs (and very handily lets them also be closed to save memory and reopened days or weeks later when required again).

Also every month or two I dump all my mobile chrome tabs over to my desktop Chrome, so that I can close all tabs on my phone.

i.e. History -> Tabs from other Devices -> Open All

Then I backup, search, and group my URL history hierarchy in the the tree-view of Tabs-outliner
