Why you can't close your tabs: the psychology of tab hoarding

Closing a tab takes one click. Deciding whether to close it does not, and that decision is what tab hoarding is made of. There are two different reasons people will not close a tab, they look identical from the outside, and they need opposite fixes.

The cost isn't the click

Closing a tab takes one click. Deciding whether to close it does not. “Will I want this again?” is a real question with a real cost, and nobody wants to pay it forty times in a row, so the tab stays. That is what tab hoarding is: not a storage problem but a backlog of unmade decisions. Every piece of advice that starts with “just close them” asks you to pay exactly that cost, which is why none of it works.

Researchers at Carnegie Mellon arrived in the same place from a different direction. Their 2021 CHI paper by Joseph Chee Chang and Aniket Kittur, “When the Tab Comes Due: Challenges in the Cost Structure of Browser Tab Usage”, found that people keep tabs open because closing them feels like losing the information, and that about 25% of participants in one part of the study had had a browser or computer crash from too many tabs. What the public discussions add is the part that is more useful in practice: the reluctance is not one thing. It splits cleanly in two.

Two reasons people won't close, and they need opposite fixes

Read enough of these threads and the explanations sort into two groups that look identical from the outside and are opposites underneath.

Group one: if it's closed, it stops existing

This is the readers — and, over and over, people who mention ADHD or autism themselves. In one 366-upvote reply the first reason listed was object permanence: once the tab is closed the person forgets the thing exists at all, however important it was. So it stays open, because being visible is the only thing keeping it alive.

Group two: if it's closed, I'll never find it again

This is the researchers. Someone in r/GradSchool described closing a paper without bookmarking it and then never finding it again — despite still remembering the keywords — and named that as the reason they now fear closing tabs. The same person mentioned having more than ten thousand bookmarks, which had plainly not helped.

What they're afraid ofWhat would actually help
I'll forget it existsVisibility. Something has to bring it back in front of them. A store they must remember to visit fails by definition.
I won't be able to find it againRetrieval. Search across everything they have had open, on any word they still remember — not another folder to file it in.

Why bookmarking doesn't fix it

Bookmarks come up in every one of these threads, and always as a dead end. One reply, with 109 upvotes, described the act as adding a bookmark to a folder you are never going to open again. The tab does not become saved; it becomes invisible.

The sharpest version of the complaint named the missing primitive outright: there is no such thing as a disposable bookmark. Bookmarks do not expire and do not disappear once they have been used, so they accumulate exactly the way tabs do — just somewhere you cannot see the pile growing.

The strongest evidence here is negative, and it comes from a site that already built the obvious feature. AO3 has a built-in “Mark for Later” list, and its readers reject it: things put there go into the void and never get read. One person said they do not use it because they know they will not go back — and then admitted, in the same breath, that they do not go back to the tabs either.

Why “collapse all tabs” becomes the next pile

OneTab is the most frequently recommended tool in these threads, and one of the twelve in our roundup of the best Chrome extensions. It also has the most consistent ending. One person reported that their OneTab now contains 252 tabs. The pile did not shrink; it moved.

Tree-style tab sidebars get a related criticism: by making a large number of tabs comfortable to look at, they make it easier to reach a hundred of them. That is not a bug in those extensions — it is what happens when a tool addresses the display of the pile rather than the decision backlog underneath it.

The rule that falls out of this: a “collapse everything” action is only useful if it comes with expiry or triage. Otherwise you have built a second inbox, and the first thing every inbox does is fill up.

One group that isn't asking to be fixed

Developers are the exception, and it is worth saying plainly because most articles on this subject quietly assume everyone wants fewer tabs. In r/sysadmin, tab count is used as a unit of difficulty — one comment sized up a Terraform problem as a 40-tab problem, and got 72 upvotes for it. Another person said they bought 64 GB of RAM mainly so they would never have to close anything.

Asked how they cope with constant context switching, the top-voted answer in r/ExperiencedDevs was, in full, “We don't” — 727 upvotes. The second was that you don't, you do one thing at a time.

For this group, a hundred tabs is a symptom of the problem being hard, not of losing control. Any product that frames “fewer tabs” as the goal is telling them their work is untidy. What they want is for nothing to break at a high tab count.

The single most useful thing we read had only 8 upvotes, in r/DataHoarder. Its point: what a tab gives you over a bookmark is not the page, it is the path you took to reach it — you can step back and branch off again. Every tool that collapses tabs saves the destination URL and throws away precisely the thing people are unwilling to lose. As far as we can tell, nothing on the market covers this.

People already invented the fix

A comment with 121 upvotes describes a ritual its author calls declaring tab bankruptcy: every couple of years, skim the most recent ten or twenty tabs, bookmark all tabs into a folder named after the date, and close everything. The honest ending is the interesting part — they are not sure they have ever gone back to one of those folders, but it felt much better.

The same relief shows up involuntarily. One person described closing tabs when the count starts making them anxious, and added that when the browser crashes and takes everything with it, they feel relieved.

Note what that means. The ritual works emotionally even though the archive is never read. The relief does not come from preserving anything — it comes from ending the backlog of decisions. Which suggests the honest feature here is not better storage. It is a way to declare bankruptcy deliberately, instead of waiting for a crash to do it for you.

What actually helps

  • Stop using tab count as the score. It measures how hard your week is, not how disorganised you are.
  • Work out which group you are in. If your fear is forgetting it exists, you need something that resurfaces it; a tidy archive you have to remember to open will fail. If your fear is not finding it again, you need search, not folders.
  • Declare bankruptcy on purpose. Pick a date, archive the lot, close everything. It works, and the evidence says you will not miss the archive.
  • Pin the handful you genuinely return to, so they stop competing with the backlog for space.

SideBoo addresses the retrieval half of this: one keystroke searches your open tabs, history, bookmarks and recently closed pages at once, so closing a tab stops being the same thing as losing it. It does not solve the visibility half — nothing here will walk up and remind you that a tab exists — and we would rather say that than pretend otherwise. Everything stays on your machine.

Where these patterns come from

Frequently asked questions

Is it normal to have 100 tabs open?

It is extremely common. A hundred is unremarkable; one person reported 1,200, and another explained that Safari caps them at 500 so they sit permanently at 498. Chrome on Android stops counting past 99 and shows a smiley face. You are not an outlier.

Why doesn't bookmarking my tabs help?

Because bookmarks never expire and never disappear after use, so they accumulate the same way tabs do — only out of sight. Bookmarking gets described over and over as a one-way graveyard; one person with more than ten thousand bookmarks said it had done nothing for their organisation.

Why do tools like OneTab stop working after a while?

Because collapsing tabs into a list moves the pile rather than reducing it — one user reported 252 tabs sitting in their OneTab. A collapse action only helps if something expires or triages what went in.

Is keeping too many tabs open an ADHD thing?

People who mention ADHD or autism do describe this pattern often, and the largest public discussion of it sits in r/ADHD. But it appears across every group, including developers and academics who raise no such thing, so it is not a sign of anything on its own. If it is affecting your daily life, that is a conversation for a clinician, not a browser extension.

How do I actually start clearing them?

The method with the most support behind it is deliberate tab bankruptcy: skim the most recent ten or twenty, bookmark everything into a folder named after today's date, and close the lot. The people who do this report that they rarely open the folder again and feel considerably better anyway.
