Tabius - Automatic Tab Grouping Assistant

The extension has a solid 4.4-star rating from 62 users and serves 4,000 users, indicating reasonable user satisfaction. The functionality aligns well with its stated purpose of automatic tab grouping. The developer domain (failab.eu) appears to be a legitimate entity, and the extension uses Manifest V3, which provides better security controls than older versions.

The primary concern is the tabs permission, which grants broad access to browser tab information and manipulation capabilities. While this permission is necessary for the extension's core functionality of organizing tabs into groups, it also allows the extension to view URLs, titles, and potentially sensitive information from all open tabs. The storage permission, while lower risk, enables data persistence that could be used to track browsing patterns over time.

Given the medium risk level, consider running this extension in a separate Chrome profile if you frequently work with sensitive information or confidential websites. Monitor the extension's behavior and review what data it might be storing. The relatively small user base (4,000) means less community oversight compared to more popular extensions. Regularly check for updates and consider alternatives if the extension requests additional permissions in future versions. The functionality appears legitimate, but the broad tab access warrants cautious use.
