In-depth safety analysis
This extension requests powerful permissions that allow it to read and alter data on any website you visit. The combination of “tabs,” “scripting,” and host access to *://*/* means it can see page content, manipulate tabs, and inject code into all pages. For a tab suspender, such access is functionally necessary—it must detect tab states, unload heavy pages, and restore them—but the scope is among the broadest a browser extension can have.
General safety guidance for a tab-management tool like this is to verify you are installing the authentic version from a trusted publisher. Extensions in this category often ask for extensive permissions, and because they interact with every site, a compromised or cloned extension could expose sensitive browsing data. Check that the developer’s website and store listing align with what you expect, and keep an eye on recent reviews for any sudden changes in behaviour.
In this case, the fact sheet shows Maintenance & Ownership as the strongest dimension (100/100), meaning the extension is actively updated and its source is reasonably clear. The weakest area is Permissions & Access (58/100), reflecting the inherent risk of granting such broad host and scripting privileges. The developer’s declared privacy practices appear sound (Data & Privacy scored 100), but the technical permissions remain a point of caution, so users should weigh the convenience against the level of trust required.
AI-assisted analysis of the documented signals above (permissions, store data, privacy practices) — explains what they mean and the risks typical for this category. Not a hands-on test.

Who's Behind Tab Suspender?
- Publisher tab-suspender.com
Public records identify the publisher, but no individual founders or a separate registered company are named — which is what holds the Publisher & Identity score back. Less public information about who operates an extension means less you can verify about their long-term accountability.
