Extension Metadata
About this extension
Version 0.4 - Form Hack Reloaded (MIT Fork)
What's New:
- Toggle hidden form inputs ON/OFF with persistent state across page reloads
- Green ● (active) / Red ● (inactive) badge visual feedback
- Auto-applies on page load via content script
How to Test:
1. Install → Click icon on any page → Red ● (inactive)
2. Click again → Green ● (active) → hidden <input type="hidden"> become visible text fields with gray labels
3. Refresh page → fields stay visible (persistent)
4. Click → Red ● → fields revert to hidden
Eval Usage (Safe):
- Required for dynamic code injection to toggle input types on arbitrary pages
- Only modifies DOM (input type/class + labels), no data exfiltration
- Matches original Form Hack behavior (MIT licensed upstream)
Test Page: Any form with hidden inputs (e.g., login pages, checkout forms)
