I would call myself a tab hoarder. FOMO. But I started using the browser setting to automatically close the tabs which have not been active in the past 7/30 days. If I have read the tab content, they should come up again in the history/search suggestions when I type in the URL/search bar. If I’m really sure I want to reference it later, I bookmark it or write it on my notes.

Also just learn to let go. I’m still having quite a number of tabs and windows open. But this auto cleanup has helped a lot.
