Description
Embedded HAR/JSON viewer. Visualizes HTTP Archive (HAR) files opened locally or online. Also features JSON tree view for HAR and any structured JSON files. Allows to switch between HAR (if available), JSON tree and plain (original) views.
Note: In order to get this viewer working with local files you have to grant the respective permission: chrome://extensions -> HAR/JSON viewer -> Details -> Allow access to File URLs.

It doesn't work at all. Yes, allow access to file URLs is on. Yes, the icon is visible at the top. Loading a HAR file just shows the JSON, nothing else. Clicking the icon for this does nothing. If there's something else to do, then that needs to be in the instructions for the extension. I see 2 others having the same problem in the Support pane. I guess the extension has rotted.
