In-depth safety analysis
This extension requests the activeTab and scripting permissions, which together allow it to inject CSS and JavaScript into the webpage you are currently viewing when you invoke the extension. This is a standard and necessary permission model for a debugging tool that needs to inspect and modify page styles in real time. The storage permission lets it save your settings locally, and contextMenus adds a right-click menu item for quick access.
For a general browser extension in the developer tools category, a typical safety consideration is ensuring you only activate it on sites you trust, as the ability to modify page appearance can be misused by malicious scripts to overlay fake prompts or alter displayed information. The developer has declared they collect user activity and website content, which is expected for a tool that analyzes page elements, but a careful user should verify the privacy policy to understand how this data is handled.
The fact sheet shows this extension has a strong Data & Privacy score, reflecting clear privacy practice declarations and a manifest V3 design. Its weakest dimension is Publisher & Identity, which suggests limited publicly available information about the developer, a common scenario for smaller or independent tool makers that does not necessarily indicate a problem.
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.
