Tab Out guide: turn your new tab page into a browser task console
An open-source Chrome extension that takes over the new tab page, groups your currently open pages by domain, flags duplicate tabs, and supports one-click jump, batch close, and save-for-later.
If you often end up with dozens of tabs open and don’t want to hunt and close them one by one, Tab Out is worth installing.
What problem it solves
Native browser tab management has two hard flaws:
- Once there are many tabs they shrink to tiny icons, and you can’t tell what they are
- There’s no “batch” ability at all — you can only close them one at a time
Tab Out takes over the new tab page and displays all your currently open pages grouped by domain as a card list. Every time you open a new tab, what you see isn’t a search box, but your current working scene.
Core features
| Feature | Description |
|---|---|
| Domain grouping | pages from the same site cluster together, with favicon |
| Duplicate flag | the same URL opened multiple times gets highlighted |
| One-click jump | click a card to switch right over |
| Batch close | close a whole group by domain |
| Read later | save the current group, restore with one click later |
Three common uses
1. Clear the field by project
When a project is done, save its dozen-odd related tabs as one group at once, then close the whole group. Restore with one click when needed. This beats bookmarks because it’s a group, not a single item.
2. Find duplicates
During research it’s easy to open the same page three or four times (entered from different entry points). The duplicate flag highlights them directly; closing the duplicates instantly frees memory.
3. See where time went
Look at which domain has 20 tabs under it, and you know where today’s time went. This feature has no UI, but the side effect is very real.
Install and configure
- Search
Tab Outin the Chrome Web Store, or find the source on GitHub and load it yourself - After installing, just open a new tab and it takes effect
- In settings, recommended to enable: focus the search box on new tab (type directly when you need to search)
Shortcomings
- Only Chromium-based browsers supported
- Once tabs exceed 80, group rendering has perceptible lag
- Grouping dimension is only domain; no custom rules
The first two are unsolvable; the third can be worked around with multiple windows: open a different browser window per project.
One-line review
It doesn’t change your habit of opening tabs, it just lets you finally see what you have open. For people who “open a lot but can’t close them,” that’s enough.
