Either way, I only get bad performance from a few tabs at a time, usually a Fandom wikia or the pinned Gmail tabs. The first can be solved with a few seconds on about:performance, and the second well... after reading this article and Gorhill's reply, I opened a Fastmail account. We'll see how it goes. But if they're really planning to put all users at risk with an automatic update, Google has finally crossed the evil line.
I also recommend periodically declaring tab bankruptcy. It feels so light and clean! For a little while, at least.
You, sir, are a gentleman and a scholar. I'm under 1000 now! (ok... 999) Deduplication of tabs is pretty useful for the Jira issues (I usually follow links from Slack). If only Jira pages would load faster.
Tab bankruptcy scares me. It's hard to know how much of it is an action I still need to take. Some of it is research I don't want have to find again, but I need to take the time to bookmark.
