In-depth safety analysis
This extension requests only the "tabGroups" permission, which lets it query, create, and modify your Chrome tab groups. This is a minimal and focused permission directly needed to save and restore grouped tabs—it does not grant access to your browsing history, cookies, or the content of pages you visit. For a tab management tool, this is a well-scoped and appropriate request, reflected in the highest possible Permissions & Access score.
General browser extensions that organize tabs typically need only tab-related permissions; a careful user should be wary of tab managers that demand broad access to all website data. Here, the developer’s privacy disclosures state data is not sold or used for unrelated purposes, which is encouraging. However, the Community Reputation score is notably low, driven by a 2.9‑star average from 39 ratings. While this doesn’t signal a security problem, it may point to user experience issues or unmet expectations—something to consider before depending on the extension.
The strongest dimension, Permissions & Access, aligns with good safety practices: the single permission matches the extension’s function without unnecessary reach. Given the low community rating, you might test the tool in a limited profile first to ensure it meets your needs reliably.
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.
