need to disable devtools.jsonview.enabled in about:config for this to work. Please consider adding it to the description of this wonderful addon.

единственное расширение, которое на header text/html преобразует в красивый json

At last a convenient way to see JSON files without opening the developer tools.

The tools I found that can really be used on Firefox are great! jsonview doesn't work properly on Firefox. I have been distressed for a long time, thank you very much.

The only one I found, that worked on Firefox Quantum 65.0.1 (64-bit).
Plus, it has good custom visual options. Great add-on!
Thank you, Mr. Lauri Rooden.

Very Good
