## Description

ZeroWebTools Companion is a secure browser extension designed to extend the capabilities of the <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/3c24d25f4ffa48738ffe297ac7a3ceedb5288cba0fe798703ff6172fc833cf05/http%3A//zerowebtools.com" rel="nofollow">zerowebtools.com</a> platform and bring a lightweight, 100% offline developer toolbelt right into your Firefox toolbar. 

All data transformations and formats are executed locally in your browser context. No data is ever sent to external servers, making it a safe choice for corporate developers handling sensitive API credentials, production logs, tokens, or proprietary code blocks.

🚀 Six Essential Offline Utilities in One Popup:
<ol><li>JSON Formatter &amp; Tree Explorer: Paste raw JSON to validate it, pretty-print it (with collapsible arrays and objects), or minify it instantly.</li><li>Side-by-Side Diff Checker: Compare two blocks of code or text files inline to highlight additions, deletions, and line-level changes.</li><li>JWT Debugger &amp; Decoder: Instantly inspect JSON Web Tokens. Decode headers, payload claims, and signatures securely offline.</li><li>Case Converter: Transform naming conventions between camelCase, snake_case, kebab-case, and PascalCase.</li><li>Base64 Cipher: Encode strings to Base64 or decode hashes back to readable plain text.</li><li>URL Encoder/Decoder: Clean percent-encoding from URL parameter strings and format query parameters.</li></ol>
🔗 Secure Platform Bridge for Advanced Tools:

Unlocks advanced capabilities on <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/3c24d25f4ffa48738ffe297ac7a3ceedb5288cba0fe798703ff6172fc833cf05/http%3A//zerowebtools.com" rel="nofollow">zerowebtools.com</a> by routing permissions securely through your local browser context:
- CORS Bypass: Execute requests in the online REST API Client directly from your local browser context, eliminating the need for proxy servers.
- Local Web Scraping: Extracts clean text nodes locally for the Smart Article Reader and YouTube Transcriber without intermediate database logging.

<ul><li>Runs completely offline in your browser's sandbox memory.</li><li>Zero telemetry, tracking scripts, or analytical cookies.</li><li>Zero server communication.</li></ul>
