OneTab for Chrome, and why the tabs keep coming back
OneTab is a free Chrome extension that closes every tab in the current window and turns them into a single page of links, which can be restored one at a time or all at once. Install it from the Chrome Web Store, pin its icon to the toolbar, and one click empties the tab strip. That is the whole product, and for a crowded window it does exactly what it says. This guide covers how it works, what the store listing and the publisher's site said when checked on October 18, 2026, which of its jobs Chrome now does without any extension, and why many people find their tab strip full again a couple of weeks after installing it. This site is run by the maker of an app aggregation browser for macOS.
What OneTab does, step by step
The flow has three parts, and the publisher's own page describes it in two sentences: when there are too many tabs, click the OneTab icon to convert them into a list, and restore them individually or all at once when they are needed again.
- Add OneTab from the Chrome Web Store with Add to Chrome.
- Open the puzzle piece Extensions menu at the right of the address bar and pin OneTab. The publisher points this out specifically, because an unpinned icon stays hidden inside the Extensions menu and the one click workflow stops being one click.
- Click the icon. Every tab in the window closes and a OneTab page opens with their titles and URLs.
From that page, clicking a link restores a single tab, and a whole group can be brought back at once. The publisher's site lists further features: export and import of tab lists, sharing a list as a web page, and organizing with folders, tasks, notes and encrypted cross browser sync. There is no signup step for the core function.
Privacy is stated in plain terms on one-tab.com. Tab URLs are not transmitted to the developers or to any other party. The single exception is the "Share as a web page" button, which uploads the list so it can be sent to someone. Domain icons in the list are generated by Google.
One warning on the same page deserves attention before anyone stores hundreds of links there:
Uninstalling OneTab will cause your browser to delete your stored tabs. Source: one-tab.com
The list lives in the extension's own storage, not in Chrome bookmarks. The publisher advises quitting and restarting the browser when OneTab fails to load, rather than reinstalling it. An export to a file once in a while is the only backup.
The store listing on October 18, 2026
Numbers on store pages move, so these are the values shown on the Chrome Web Store listing on the date above.
| Item | Value shown |
|---|---|
| Publisher | OneTab Ltd |
| Users | 2,000,000 |
| Rating | 3.8 out of 5, from 14.6K ratings |
| Version | 2.24 |
| Updated | October 11, 2026 |
| Size | 2.87MiB |
| Languages | 48 |
| Badges | Featured, follows recommended practices |
The listing also states that the developer has disclosed it will not collect or use user data, and that the publisher has no history of violations. Older articles about OneTab often quote a rating in the mid 4 range. The current figure is lower, and the store notes that ratings are updated daily. Reading the most recent reviews after a new version ships is a reasonable step for anyone deciding whether to install now.
The headline claim on both the listing and the site is a memory saving of up to 95 percent. The site backs it with a before and after pair: 1981 MB in use before, 99 MB after. The mechanism is simple. OneTab closes the pages and keeps only their addresses as text, so the saving is the memory those pages were using. Closing the same tabs by hand would free the same memory. What the extension adds is a reliable place to find them again, which is what makes people willing to close them at all.
Two things follow. The size of the saving depends on what was open: video, maps, design tools and live dashboards free a lot, while plain text articles free much less. And restoring is a reload. Bringing back fifty tabs starts fifty page loads, so the saving only lasts while the tabs stay in the list.
What Chrome does now without an extension
Several of the reasons people install OneTab are handled natively in current Chrome. Trying these first avoids running two tools for one job.
Memory Saver
Chrome deactivates tabs that are not in use and reloads them when they are opened again. The setting lives at Settings, Performance, Memory Saver, with three levels: Moderate, Balanced (recommended), and Maximum, which differ in how soon a tab becomes inactive. A list of sites can be kept active with "Always keep these sites active". Google's help page on Memory Saver also lists what prevents deactivation, including active audio or video, screen sharing, page notifications, active downloads, partially filled forms, and pinned tabs.
That last list is useful. Chrome deliberately does not put to sleep the tabs that would break if put to sleep, such as a half filled form or a chat that sends notifications. OneTab closes everything in the window regardless.
Tab groups
Tabs can be collected under a colored, named group that collapses to its name or a colored circle. Closing a group does not delete it. According to Google, a closed group is saved in the bookmarks bar or the menu and can be reopened.

Vertical tabs and Tab Search
Right click a blank part of the tab strip and choose Show Tabs Vertically to move the strip to the side, where full page titles are visible and the list scrolls. Tab Search is pinned to the strip by default and opens with Command, Shift and A on a Mac. Typing @tabs in the address bar searches open tabs too.
OneTab, a session manager, and Chrome compared
OneTab is not the only extension in this space. The search results for this query also show Tablerone, a free tab session manager. Its site describes saved workspaces, visual bookmarks with screenshots, tags and notes, and a tab sleep feature that discards idle tabs to free memory. It states no accounts are required and that it is funded by user donations. The features below come from each product's own pages and from Google's help, checked on October 18, 2026.
| OneTab | Tablerone | Chrome built in | |
|---|---|---|---|
| Price | Free | Free, donation funded | Free |
| Collapse all tabs to a list | Yes | Yes | No |
| Put idle tabs to sleep automatically | No, closes them | Yes, tab sleep | Yes, Memory Saver |
| Organizing saved tabs | Folders, tasks, notes | Workspaces, tags, notes | Tab groups |
| Sync across devices | Encrypted cross browser sync | Mobile sync | With Google Account sync |
| Export to a file | Yes | Yes | Bookmarks export |
| Stored where | Extension storage | Extension storage | Google Account and bookmarks |
The honest summary is that the three overlap heavily. OneTab is the simplest and the most widely installed. Tablerone layers sessions, previews and sleep on top. Chrome itself now covers sleeping tabs, grouping and searching. A good test is to turn on Memory Saver and vertical tabs for a week and see whether the problem that sent the search remains.
Details for Tablerone are on tabler.one.
Why the tabs keep coming back
The common pattern goes like this. The strip is emptied, the machine is quiet, and two weeks later the strip is full again while the OneTab list holds several hundred entries nobody opens. That is not a defect in the extension. It usually means the tabs that were collapsed and the tabs that cause the clutter are two different groups.
A window of forty tabs tends to hold two kinds of thing.
- Research. Search results, half read articles, documentation. Nothing is lost by closing them, because the address is all that matters. These are an excellent fit for a list.
- Apps that stay open all day. Gmail, Slack, Notion, a calendar, an admin panel. These cannot be collapsed without consequences. A collapsed chat stops sending notifications, and a collapsed draft loses whatever was typed but not saved, since the list keeps only the URL and the title.
Collapsing the whole window treats both groups the same way. The research disappears, which helps. The apps disappear too, which hurts, so they get restored within the hour. Restoring them brings back the cue to open more tabs alongside them, and the strip refills. Meanwhile the list grows with each cycle.
Notice that Chrome's Memory Saver exclusions line up with the second group almost exactly: notifications, partially filled forms, pinned tabs. Google's own design treats those tabs as different from the rest. A workflow that does the same tends to hold up.
Logins are a third layer that no tab tool touches. Two Gmail accounts in one Chrome profile still sign each other out, whether the window has five tabs or fifty. Account separation in Chrome happens at the profile level, which means a second window, not at the tab level.
Keeping the list useful
If OneTab stays, a few habits stop the list from turning into a second junk drawer.
- Collapse research, not apps. Before clicking the icon, move the daily apps to a separate window, so only research goes into the list.
- Name the group at the moment of collapsing. A group titled after the project is findable later. A group titled with a date is not.
- Run a weekly delete pass. Anything that survives two passes unopened is a bookmark, not a tab. Move it and remove it from the list.
- Export monthly. The list lives in extension storage, and an uninstall or a damaged profile takes it along.
These are small costs, and they decide whether the list is trusted. A trusted list is one people actually collapse into. An untrusted one is the reason tabs stay open "just in case".
Giving the daily apps their own place
The remaining problem is the handful of apps that are open every working hour and share a strip with disposable research. Pinned tabs help, but they still sit in one profile, with one set of logins, in the same row as everything else.
A browser that keeps each web app in its own window takes those apps out of the tab strip entirely. Gmail, Slack and Notion sit in a fixed sidebar, each with its own storage, so research tabs can pile up and be cleared without touching them. The Workspaces page explains how separate sets of apps and sign ins are kept apart, including more than one account for the same service. Plans and limits, including a free tier of one workspace with three apps and Chrome extension support, are on the Pricing and FAQ pages.
What to change first
Turn on Memory Saver and vertical tabs, then pin the apps that are open all day. Keep OneTab for research only, name each group when collapsing, and export the list monthly. If the pinned apps still crowd the window or the accounts keep colliding, move them into SpaceDeck and leave the tab strip for reading.
Frequently asked questions
Is OneTab free, and does it need an account?
The core function is free and the publisher states no signup or registration is required. The Chrome Web Store listing showed 2,000,000 users on October 18, 2026. Optional features such as encrypted cross browser sync are described on the publisher's site.
Are saved tabs lost if OneTab is removed?
Yes. The publisher states that uninstalling OneTab causes the browser to delete the stored tabs, because the list is kept in extension storage rather than bookmarks. Use the export function before removing it, and restart the browser rather than reinstalling if it fails to load.
Does Chrome already do what OneTab does?
Partly. Memory Saver puts unused tabs to sleep and reloads them on demand, tab groups can be closed and reopened later, and Tab Search finds any open tab. What Chrome does not offer is a single page that collapses a whole window into a text list of links.
Why does the tab strip fill up again after using OneTab?
Usually because the apps open all day get collapsed with the research and then restored within the hour. Keep those apps in their own window, use OneTab only for research tabs, and the strip stays clearer. Separate logins for the same service still need separate Chrome profiles or an app based browser.
