how do you see how many tabs you have open, an extension? i have tab session manager and it shows i have 80 tabs. about 60 of those are ephemeral, and the other 20 i'd have open on a new browser anyhow (email x3, goog cal, caldav cal, nextcloud files, router, local and remote proxmox, navidrome, the documentation server, etc) everything else is superfluous. although i'd probably be a bit sad if i lost all my tabs right now; hence tab session manager.
