Is JSON Viewer Safe? — Extension Safety Profile

This extension requests only the "storage" permission, which allows it to save settings locally on your device. It does not ask for access to your browsing data, tabs, or any website content. For a JSON viewer, this is an unusually minimal permission profile—most tools that actually parse and format JSON on pages would need broader access to page content at some level. Here, the limited permission scope suggests the extension may operate without injecting into arbitrary pages, keeping its potential reach very narrow and well within safe expectations.

Developer tools in general can be vectors for supply-chain attacks if they request sweeping host permissions or execute code from remote sources. A careful user should verify that any extension claiming to process page data actually requires the permissions it asks for. With only storage access, this extension cannot read or modify the websites you visit, greatly reducing the potential for data exposure or malicious injection even if the extension itself were compromised.

The strongest safety dimension for this extension is Permissions & Access, scoring 100 out of 100, which reflects its extremely limited and safe permission request. The weakest dimension is Maintenance & Ownership, with a score of 10 out of 100. This may indicate concerns such as a single-developer project with infrequent updates, limited track record, or minimal public engagement—factors that can affect long-term reliability and responsiveness to security patches. Combined with the very low permission risk, the overall safety grade remains a B, suggesting the extension is low-risk in operation but users should be aware that ongoing support could be uncertain.
