I have like 50 tabs across various groups. A lot are things I want to read but haven't gotten to yet, a few are just work (email, slack, onedrive). Some are for job apps. I do restore my tabs lol.

Bookmarks are messier because the papers aren't necessary all the time and their citations are in endnote. But if I bookmarked all the papers I'd have some thousands which is too messy in a browser.
