In-depth safety analysis
This extension requests permissions that are typical for a font customization tool. The activeTab permission allows it to interact with the current page only when invoked, while scripting enables it to inject code to apply custom fonts. The fontSettings permission can adjust browser-level font defaults, and storage saves your preferences locally. This scope is normal for an extension that modifies website fonts on demand.
As with any extension that can read and alter page content, a cautious user should consider the publisher’s transparency. The developer’s privacy declarations state data is not sold or used for unrelated purposes, but the lower Publisher & Identity score (60%) suggests limited publicly available information about the developer. It is wise to verify the extension’s website and support channels before installing, especially when granting content-modification permissions.
The extension’s strongest dimension is Maintenance & Ownership, indicating it is actively updated and its ownership is clear. Combined with a solid overall safety grade, this suggests the codebase is well-managed. Still, users should remain aware that any extension with scripting access could potentially see sensitive page content, so it is prudent to limit such permissions to trusted sources.
