Or even save all your open tabs as a MAFF archive! Then you can read them offline. I like to add them to my todo list and then read them when I turn of my networking so I don't get lost down a hacker news rat hole. Dunno if chrome supports that, but Firefox (obviously) does[0].

That was my old approach, but it quickly leads to a very cluttered folder full of dozens of "New folder" folders, and personally I never look back at any of them because it feels like a junk drawer.

OneTab's features for organizing and prioritizing are so much better when you're dealing with hundreds/thousands of tabs. Also you can browse by the date a tab group was added on.
