JSON Formatter automatically formats and prettifies JSON in Firefox. It comes with support for syntax highlighting and over 60 themes. It also makes links clickable automatically and has multiple modes to view JSON, including Parsed Mode, Formatted Raw Mode, and Raw Mode. Note: This extension requires additional configuration to work. As Firefox already has an inbuilt JSON Formatter, you need to disable it for this extension to work. to do so, go open "about:config", search "devtools.jsonview.enabled", make it "false" to disable the default JSON Formatter and you are ready to go.
