Debugger port doesn't prove extension code executed (Firefox opens it). New approach: - Extension writes marker to browser.storage.local on init - Test script checks Firefox profile for storage.js file - Verifies _rentgen_init_timestamp and _rentgen_init_iso keys This proves: - background.ts executed - browser.storage.local.set() succeeded - Extension has working browser API access Non-invasive: storage is only used for automated tests 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
