Maybe it's just my ADHD, but I can't even imagine managing that many tabs.
In my workflow, I start a project, then keep opening new tabs as I need to look things up, frequently moving tabs between multiple browsers spanning my 32" monitor. So long as I'm working on that problem, I just keep opening new tabs.
Then, when I've finally squared away the section of the project I was working on, I usually just close the browser entirely and start fresh.
Needing to manually sift through the 80+ tabs I chaotically opened in the last hour or so to figure out what's worth keeping? Hell no. That's what browser history is for. It's Etch-a-Sketch time! Shake it clean and start fresh.
