I also suffer from “tab overflow” so I convert them to bookmarks. Unlike tabs, bookmarks use minimal browser resources – just an entry in an SQLite database.
Every so often, I use Ctrl-Shift-D to save all the tabs in the current window to their own folder in Bookmarks. I follow this with Ctrl-Shift-W which closes all the tabs in the current window. I repeat this for each browser window containing multiple tabs.
That way, the tabs that had been open are stored in a loosely organised way and are easily retrieved if I ever feel the need to. More often than not, I won’t look at them again but they’re there if I want to.
