When it works it is very nice. However it doesn't always work reliably. I've just opened a clearly JSON formatted file ending with .json in the browser's regular window and it has not been picked up by this extension. It's happened a few times recently.

Suddenly degraded. Only "pretty print" function is shown in UI, but others are not.

Seems to work, even when you don't want it to. For example, visiting namecheap.com. It replaces the entire webpage with JSON Viewer because it found some hidden JSON somewhere on the page. Maybe check the response MIME type first?Developer doesn't seem interested in fixing it.
