Is CrxMouse: Mouse Gestures Safe? — Extension Safety Profile

This extension requests broad permissions that match its function of interpreting mouse gestures on any webpage. The host access to all URLs and permissions like scripting, webNavigation, and webRequest allow it to read and modify page content, detect navigation, and inject its own code to recognize gestures and execute commands. It can also read and write to the clipboard and access your bookmarks, which is typical for productivity tools offering shortcuts for copying, pasting, or opening saved links. The scope is extensive but expected for a gesture-control extension that must work across every site you visit.

For a productivity tool with such deep access to all web activity, a careful user should be aware that any flaw in the extension's code or a supply-chain compromise could expose everything you type, view, or copy online. The developer's declared data collection includes web history and user activity, which is logical for a gesture recorder but means your browsing patterns are being gathered. Users should verify that the extension's settings allow them to control or disable any telemetry they are not comfortable sharing.

The fact sheet shows a strong Maintenance & Ownership score, indicating the extension is actively updated and its publisher is well-established. The weakest dimension is Permissions & Access, reflecting the very broad set of capabilities requested. This combination suggests a legitimate, well-maintained tool that inherently requires high trust because of its invasive permission model.
