Having gone through the 'daily' group's tabs, I now have a bunch of new unread tabs and have got rid of those tabs that didn't have anything interesting to read. This might leave me with, say, six tabs.
As I read those tabs, I close the tabs. Eventually I might end up with no tabs and close the browser, or I might leave that last tab open so that the browser itself remains open.
Depending on time available, or my own inclination, I might open another section called (say) 'Tech News' which has about half a dozen sites and repeat the above procedure.
Tabs only remain open if there is something not yet read in them, or if I using that page for reference. As soon as the tab is 'used up' it is closed.
This comes a bit over 10 years after writing an extension that capture tab activity into an rss feed, which i wrote for a Mozilla Design Challenge for 2009. I've wanted to do a lot more, but haven't returned to the problem space until recently. https://blog.mozilla.org/labs/2009/05/introducing-the-design...
Ideally I create a separate webapp that lets me browse old windows, & figure out out to ex-post save/file/tag pages.
But normally, browsers just resume my tabs, so been rocking the same'ish tabs groups forever.

If I have more open tabs than that, I likely won't be able to find them anyway.
