Terms of Use

Last updated: 4 October 2026 · Applies to ThreeTabs 1.0.0 and later

In short: ThreeTabs is free, open-source software provided as-is. Use it, change it, share it. It deliberately closes new tabs, so don't rely on a tab you just opened to hold unsaved work.

1. Acceptance

By installing or using ThreeTabs (the "Software") or this website, you agree to these terms. If you do not agree, do not use them.

2. License

The Software is released under the MIT License. You may use, copy, modify, merge, publish, distribute, sublicense and sell it under that license's conditions. In any conflict between these terms and the MIT License regarding the source code, the MIT License prevails. The name "ThreeTabs" and its logo identify the original project. If you publish a modified version, please make clear that it is a fork.

3. What the Software does

ThreeTabs limits the number of open tabs. When you are at the limit, it closes newly opened tabs and windows automatically, or, if you choose that mode, loads the new link in the tab you came from. It does not close tabs that were already open.

4. Your responsibility

5. No warranty

THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NON-INFRINGEMENT. The developer does not guarantee that it will be error-free, uninterrupted, or compatible with every browser version or other extension. Browser changes may affect behavior.

6. Limitation of liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE DEVELOPER AND CONTRIBUTORS ARE NOT LIABLE FOR ANY CLAIM, DAMAGES OR LOSS (INCLUDING LOST DATA, LOST PRODUCTIVITY OR LOST TABS) ARISING FROM THE USE OF OR INABILITY TO USE THE SOFTWARE. Nothing here excludes liability that cannot be excluded by law.

7. Donations

Support through Ko-fi is voluntary, is a gift, and unlocks nothing. The Software stays free and fully functional. Donations are processed by Ko-fi under its own terms and are generally non-refundable.

8. Third parties

ThreeTabs is an independent project. It is not affiliated with or endorsed by Google, Microsoft, Mozilla, GitHub or Ko-fi. All trademarks and logos belong to their owners. The Ko-fi logo used for the support link comes from the Simple Icons project.

9. Privacy

How data is handled is described in the Privacy Policy. In short: no tracking.

10. Changes and termination

These terms may be updated. The current version is always here, with its date at the top, and the history is in the repository. Continued use after a change means you accept it. You can stop at any time by uninstalling the extension.
