Does Not Work With Local JSON Files

[ThePieMonster]

I was attempting to use this extension to view a local json config file.

The main json config blocks { } are not separated by a trailing comma { }, so this seems to break your extension.

I also can't make it work with any local files. The extension config has the option for incognito, but not local.
