Is JSON Viewer Safe? — Extension Safety Profile

The JSON Viewer extension requests the activeTab permission, which allows it to read and modify the content of the currently active tab only when you invoke the extension. The storage permission lets it save settings locally. The broad host permission means the extension can access data on any website you visit, which is typical for a tool designed to detect and format JSON wherever it appears, but users should be aware it grants the ability to read page content across all sites.

For any general browser extension with wide host access, a careful user understands that the extension could theoretically read sensitive information on pages. It is good practice to only grant such permissions to extensions from developers you trust and to review privacy disclosures. The publisher has declared that data is not sold, not used for unrelated purposes, and not used for creditworthiness, which are positive signals.

The weakest dimension for this extension is Publisher & Identity, indicating less transparency or verification around the developer’s background. The strongest dimension is Maintenance & Ownership, reflecting active upkeep and version management. With a high community rating and moderate user base, the extension appears well-received, but the publisher identity gap may warrant extra scrutiny from privacy-conscious users.
