Is JSONVue Safe? — Extension Safety Profile

JSONVue requests only the contextMenus and storage permissions. This lets it add a right-click menu option (for example, to format selected JSON) and save a few user preferences locally. It does not have permission to read or alter the content of web pages unless you actively trigger the context menu, so the scope is minimal and typical for a lightweight JSON viewer that works on demand.

General safety considerations for browser extensions in this category include supply-chain risks if an extension is not actively maintained. JSON formatters can sometimes request broad host permissions to auto-detect JSON, which this one avoids. A careful user should note that even low-permission extensions can become a vector if updates stop and a vulnerability is later discovered. The Maintenance & Ownership score here is the weakest dimension, so it is wise to keep an eye on the extension’s update history and have a plan to switch if patches cease.

The strongest dimension is Data & Privacy, where the developer has declared that data is not sold or misused, and the tiny permission set aligns with that. The Community Reputation is also solid, supported by a large user base and high rating. The real caution is the low Maintenance & Ownership score, which suggests infrequent updates or limited publisher track record, making up-to-date security a less certain long-term promise.
