In order to use the plugin, it requires to modify the value of **devtools.jsonview.enabled** to **false** in the page **about:config** .

firefox version: 57.0.3
JSON lite version: 17.12.2

doesn't work at all! Shows white page. Even though source is valid JSON and header set correctly.
Linux 3.16.0-4-amd64 #1 SMP Debian 3.16.51-2 (2017-12-03) x86_64 GNU/Linux
Firefox ESR 52.5.2 (64-bit)

Simple, fast, reliable.
What else could be need for it?

I was looking for replacement for JSONview that stopped working in FF 57.
This one looked fine to me, though, it sometimes feels overloaded with all those guidelines and size info.

The other problem I've found, it doesn't work with "data:" protocol, so I can't use the extension to prettify big one-line JSON. So, typing something like:

data:application/json,{"test":"test"}

in the address bar just gives me the one-line text. Hope, this could be fixed.

Simple and useful.

The formatted JSON looks pretty, but on large files it takes a long time. The addon prints its progress as a percentage in the tab title, but it is still very very slow. You cannot search within the file before it is finished rendering.

JSON Lite will automatically start formatting any JSON document. Since that can take a long time I would prefer if I can activate it only when I need it. Another addon, Basic JSON Formatter, does so by adding an icon in the address bar on JSON documents.

I really love the number of properties. Maybe they could be showed on hover only, but that just a little suggestion.

Great tool, fast and simple.

really good!

Very easy to use great

It's ok

Thanks for creating a great json formatter! Really appreciate the field counts and sizes, which other json formatters don't have! One thing that this addon is missing is supporting additional Content-types since in some cases those are needed. It would be great if a "Preferences" field can be added where one can add additional content-types to be considered as json

好！！！！！

very handy , auto display , colored and formatted very well
thanks

Beautiful JSON display. Really great addon!

Fantastic addon. Great job! Thank you very much.
