In general, if data we are working with is considered "sensitive" for any reason (proprietary, PII, etc.) I always use local tools with it. I did notice recently that a coworker used the Firefox JSON viewer to display a JSON file nicely where this JSON file contained PII. They assured me that it simply renders the local data and there is no security concern here. I read a few Firefox docs trying to confirm this, but didn’t find anything conclusive.
Will using a browser’s JSON viewing tool to display JSON files expose the data to a security risk? Obviously, what is considered a security risk is very dependent on context — I’m just trying to confirm if using the browser in this way means that the JSON data could potentially be accessed by another user. In comparison, I use my IDE to format JSON files to make them easier to read.
