I appreciate this advice, but FWIW my tab habit is more a product of curiosity and time constraints, than any kind of compulsion or control issue. More of a "read-it-later-maybe" queue.

I'll open tabs for any possibly-interesting HN story, for example, and then come back later and read maybe 25% of them, often when the comment threads are still short, and almost always when only one hemisphere has had time to weigh in. Then I'll come back the next day and reload the page for new comments. Or I'll close the tab if the topic wasn't as interesting as I hoped, or if the comments are dominated by a boring tangent.

Periodicaly I sweep through the older tabs that I've never read. Some have expired in their currency. Some are reassessed for interestingness and dispatched quickly. Others are left for future sweeps.

It may not be neurotypical, but I don't think it's ADHD. :)

I should note: this is on my personal/non-sensitive browser profile. My primary work profile is usually fewer than 1000 tabs and is more actively-pruned, but generally reflects things that are still in current ongoing work. And my personal/sensitive profiles only contain a handful of tabs each, things like pending order invoices, etc.
