My take - some of us leave tabs open way too long because we fear not being able to get back to those sites again… it’s loss aversion. Tabs aren’t the core problem per se, it’s recall. We need to solve the “I want to get back here again” problem.
I primarily use Brave and effectively start fresh every day. I might get up to 20 open tabs at any given time, and I sometimes use tabs as a sort of Inbox that needs to be cleared. But sometimes, it’s best to declare tab bankruptcy and start over.
