I was tipped off about OneTab many years ago and I have been an ardent user ever since. Not only does it save memory in the browser (er..um..ahem...Chrome!), but it is a neat way to save open tabs for later, organized initally by the date and time you saved it. Plus, you can also go into one tab and move various saved pages around, in case you want to customize/group as you see fit. Nice option for links that you might need again in the near future, but not worth preserving for a later date in Pocket.
