In-depth safety analysis
This extension can read and change data on any website you visit because of the host permission. For an EPUB reader, this broad access is expected, as it needs to detect and open ebook files wherever they are hosted. The declarativeNetRequest permission lets it modify network requests, which could be used to redirect downloads or block certain content. The downloads permission allows it to save files to your computer, a normal requirement for an ebook reader that manages your library.
General browser extensions that handle files and have wide site access should be treated with caution. A careful user should know that any extension with can technically see the content of all pages, including sensitive ones like email or banking, if it chooses to. For ebook tools, it is wise to confirm the extension only activates on ebook file types or when you click its icon, rather than running on every page by default.
Based on the fact sheet, this extension's strongest dimension is Community Reputation, suggesting a generally positive user experience among its large user base. The weakest dimension is Maintenance & Ownership, which indicates potential concerns about how actively the developer updates the code or how transparent the publisher's identity is. This combination means the extension is popular and functional, but users might want to check if it receives regular security patches.
