I also recently closed ~8k.(Yes, mostly HN/lobsters/news and usually things I found interesting in the past ~6 months) For firefox users: there's a nice little addon called LoadTabOnSelect3. Without it firefox crashes to the point where you can't recover a session if firefox tries to impossibly load thousands of tabs on a machine(ram amount is irrelevant). The feature you're talking about is found in many addons, I believe also in the one i mentioned. Don't hold your breath waiting for Mozilla to implement good things quickly (though they're much better in that regard than Google: which removes features and makes the web experience worse)
