In-depth safety analysis
The extension requests permissions that allow it to read and modify the current page when you activate it (activeTab), add items to the right-click menu (contextMenus), read your clipboard contents (clipboardRead), store settings locally (storage), and access your screen dimensions (system.display). For a speed reading tool, activeTab and storage are expected, and context menus and display info are common for convenience and layout. The clipboardRead permission is less typical for this category; it could be used to import text from the clipboard into the reader, but it also means the extension can read any text you have copied when it is invoked.
Reading mode and speed reading extensions generally have access to the text of pages you visit, so a careful user should only install them from developers they trust. A malicious extension in this category could capture sensitive page content. Additionally, extensions that modify page appearance may occasionally interfere with how sites function. The clipboardRead permission adds a layer of sensitivity, as it can access data you might not intend to share with a reading tool. Users should consider whether the convenience of pasting text outweighs this access.
The strongest safety dimension for this extension is Permissions & Access, indicating that the requested capabilities are relatively focused and not overly broad for its purpose. The weakest dimension is Publisher & Identity, which reflects that the developer is an individual with limited public identity verification. This is common for smaller extensions and does not imply wrongdoing, but it means trust relies more heavily on community reputation and reviews rather than a known organizational track record.

Public records identify the publisher, but no individual founders or a separate registered company are named — which is what holds the Publisher & Identity score back. Less public information about who operates an extension means less you can verify about their long-term accountability.
