Is Tab Suspender | The Great Suspender 2026 Safe? — Extension Safety Profile

This extension can suspend inactive browser tabs to free up system resources, which is a typical function for its category. To do this, it requests broad permissions. The combination of host access to all websites and "file://" URLs with the "scripting" and "tabs" permissions means it can read and modify the content of any page you visit, including local files. While this level of access is necessary to save and restore tab states, it is highly extensive. The "cookies" permission also allows it to read and manage cookies for any site. The declared privacy practices indicate the developer says data is not sold or used for unrelated purposes.

Users of tab management extensions should be aware that these tools inherently have deep access to your browsing activity. Even when you are not actively interacting with a suspended tab, the extension can potentially see the page URL and content. A careful user should consider whether the convenience of tab suspending is worth granting such broad and persistent oversight of their web history and file access to a third-party extension.

The fact sheet shows this extension scores perfectly on maintenance and ownership, indicating it is actively managed and updated, which is a positive sign. However, the weakest dimension is its permissions and access profile, receiving a notably low score. This reflects the extensive and sensitive nature of the access it requires relative to what is typical or minimally necessary, creating a significant trust requirement in the publisher's handling of your browsing data.
