Simple and effective

Very nice extension, it does exactly what I was looking for, the only problem is that the icon in the url bar doesn't honor the dark theme, so using the dark theme the icon is not visible. Once fixed this issue it will be 5 stars for me.

也许是我没有找到使用方法，无法使用。

Nice colors and works out of the box without extra configuration steps

firefox 57 can't run

Simple, user-friendly and fast; recommends a thousand times!

I regularly need to work with large files. This addon have no trouble formatting 1 MB files instantly. You can also select and copy text from the formatted JSON wihtout getting any garbage characters. Does exactly what it says, thanks for a great plugin!
