## Description

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.
