Virtual Json Viewer Firefox

Virtual Json Viewer

By: PS
JSON browser extension with virtual DOM, search and JQ filtering

Features & Capabilities

Virtual JSON Viewer is a lightweight, ultra-fast browser extension for inspecting and interacting with JSON. It uses a virtual DOM for high-performance rendering, supports full-text search, JQ filtering, JSON Lines, shareable URLs, customizable themes and settings, prettify/minify, raw JSON view, and JSON download. Keyboard shortcuts speed up navigation and common tasks.

Important: Firefox's native JSON viewer must be disabled (set devtools.jsonview.enabled to false). JQ filtering relies on WebAssembly and may be restricted by a website's Content Security Policy. For keyboard shortcuts, FAQ, and to report bugs or suggest features, visit the project's GitHub repository.

Perfection.

Hunted this down when the built-in Firefox reader kept hanging on me during a rushed development project with medium-large. Not only did this plugin not hang like the built in FF viewer, it provides an excellent interface to learn `jq`, transform the data, perform basic text queries, and save output.

Is Virtual Json Viewer Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Virtual Json Viewer requires a few sensitive permissions. Exercise caution before installing.
