If you have too many tabs open right now, you're in good company. Somewhere behind this page there's probably a recipe you meant to cook, a hotel you were comparing, two articles you'll "get to," and a product page you've been circling for a month. You know closing them would feel lighter. You also know you won't.
I build a saving app, so I should be immune to this. I'm not. The last time I opened the tab switcher on my phone, it was a few hundred deep, and I couldn't have told you what most of them were. But I would have defended every single one.
That's the interesting part. Tab hoarding isn't really about tabs. It's about what we use them for, and what we're afraid will happen when they're gone.
Why you keep too many tabs open
In 2021, a team at Carnegie Mellon's Human-Computer Interaction Institute ran the first in-depth study of browser tabs in more than a decade. Their conclusion, published at CHI 2021, was that tab overload is common because tabs do several jobs, and do all of them poorly.
People told the researchers they kept tabs open as reminders, or because they feared they'd have to search for the information all over again. The team called it a "black hole" effect: the belief that anything closed, or even moved out of sight, is gone for good. As the study's lead, Aniket Kittur, put it, "People feared that as soon as something went out of sight, it was gone."
That fear has a real cost. About a quarter of participants in one part of the study said their browser or computer had crashed from too many open tabs. And that's just the visible cost. The quieter one is the low hum of unfinished business every time you see that crowded strip of favicons.
So when you ask yourself "why do I keep so many tabs open," the honest answer is usually: because a tab is the only place I trust to hold this thought.
A tab is a to-do item with the verb missing
Every open tab is a sentence with a word missing. Read this. Buy this, but after payday. Compare this with the other one. Reply to this. Send this to my sister.
The tab holds the place, but not the intention. A week later you see it and the verb is gone. You don't remember why it mattered, only that it did, so closing it feels like breaking a promise you can't quite recall making.
This is why tab overload grows instead of shrinking. Each tab costs nothing to open and something to close, because closing requires a decision: is this done, or is it worth keeping somewhere else? When there's no good "somewhere else," the default answer is to leave it open. Multiply that by a few months and you have a browser that's really a junk drawer with a URL bar.
Phones are where tabs go to hide
Desktop tab hoarding is at least visible. You can see the tabs shrinking to slivers. On a phone, they pile up out of sight.
Every link you tap in a messaging app, every search result, every "open in browser" from social media can quietly add a tab. Mobile browsers rarely nag you about it. You just never see the count unless you go looking, and by then it's a scrolling grid of tiny screenshots of pages you don't remember visiting.
The good news is that phones are also where the easiest fix lives. On an iPhone, Safari can close old tabs for you: in Settings, open Safari (on recent versions of iOS it sits under Apps), find Close Tabs, and choose After One Day, After One Week, or After One Month. It's set to Manually by default, which is how most of us end up with hundreds. A week is a good middle ground. If you haven't looked at a tab in seven days, it wasn't holding anything you were actively using.
How to stop keeping tabs open without losing anything
You don't need a new personality. You need a few small rules that make closing a tab feel safe.
- Write the missing verb. If a tab genuinely matters, give it one line somewhere: "Compare with the green one before Friday." If you can't come up with the line, you have your answer.
- Group by task, not by topic. Chrome and Safari both support tab groups. A group called "Lisbon trip" is useful. A group called "Articles" is just a smaller junk drawer.
- Turn on auto-close on your phone. It's the most useful single setting for mobile tab overload, and it takes ten seconds.
- Hold a closing ceremony. Once a week, close everything. Before you do, skim for the two or three tabs you'd actually be sad to lose and save those properly. Everything else was a passing thought, and passing thoughts are allowed to pass.
- Save the few that matter somewhere you can search. This is the step that decides whether the others stick. If "saving" means dropping a link into a bookmarks folder called Misc, your brain knows that's just another black hole, and it will keep the tab open instead.
That last point deserves more than a bullet.
The real fix is a place you trust
There's a lovely bit of research on this. In 2015, psychologists Benjamin Storm and Sean Stone found that saving one file before studying another helped people remember the new material better. "Saving acts as a form of offloading," as Storm put it. Your mind can let go of the old thing and make room for the new one.
But the effect had a condition. When people were told the saving process might not be reliable, the benefit disappeared. Offloading only works when you trust the save to come back.
That's tab hoarding in a nutshell. The open tab is the only save most of us trust, because we can see it. Bookmarks feel like a filing cabinet in a basement. Read-later lists fill up and go stale. So we keep the tab, and keep paying for it in clutter and crashes.
What makes a saved page trustworthy is not the act of saving. It's getting it back later without remembering exactly what it was called. Most of the time you'll remember the gist ("that article about caffeine and sleep," "the hotel with the rooftop pool") rather than the headline or the site. A place that can only match exact titles fails you exactly when you need it, which is why searching by meaning instead of keywords matters more here than any folder structure.
If a page is already gone, you're not completely out of luck either. Here's how to find a website you visited months ago using your history and a few tricks.
Where Reminari fits
This is the problem I built Reminari around, though for phones rather than desktop browsers. When a tab is worth keeping, you share it to Reminari from the share sheet and close the tab. The link is saved with the page's title, description and preview image when the site provides them, and Reminari can write a short summary with the key points, so a week later you can see why you kept it.
Then, when you need it, you don't scroll. You search the way you remember, or you ask: "what was that article about sleep and caffeine?" Reminari answers from your own saves and shows you which ones it used.
It won't import your open tabs, and it isn't a desktop app. It's a place on your phone you can trust enough to finally close the tab. It's Android first, with iOS in active development, and you can join the early access list.
Close a few tabs today. The ones that matter will be easier to keep once they have somewhere better to live.
Frequently asked questions
Is it bad to have too many tabs open?
It can be. Open tabs use memory and battery, and in Carnegie Mellon's 2021 study about a quarter of participants in one part of the research said too many tabs had crashed their browser or computer. The bigger cost is usually mental: a crowded tab bar is a list of unfinished decisions you see every time you look at the screen.
Why do I keep so many tabs open?
Most people keep tabs open as reminders, or because they're afraid they won't find the page again once it's closed. Researchers call this the "black hole" effect. The fix is less about willpower and more about having a reliable place to put the few pages that matter.
How do I close all my tabs at once on a phone?
In Safari on iPhone, touch and hold the tabs button and choose the option to close all tabs. In Chrome on Android, open the tab switcher, tap the three-dot menu, and choose Close all tabs. Save anything you need first.
What is tab hoarding?
Tab hoarding is keeping dozens or hundreds of browser tabs open because closing them feels risky. It's a cousin of digital hoarding: the pile grows because saving is easy and getting things back is hard.
Does Safari's auto-close setting delete my bookmarks?
No. Close Tabs only affects open tabs that you haven't viewed within the period you choose. Your bookmarks, Reading List and history stay where they are.
