// Outlook Web Inbox Count Extension v1.4
// Changelog v1.4:
// - Added outlook.cloud.microsoft to manifest matches (Microsoft migrated Outlook Web to new domain)
// Changelog v1.3:
// - Fixed Firefox compatibility by adding browser_specific_settings to manifest
// - Fixed bug where findTotalItems() wasn't returning values due to forEach callbacks
// - Changed forEach loops to for loops to enable proper return statements
// - Extended retry mechanism with more attempts (1s, 2s, 3s, 5s, 8s, 10s, 15s, 20s)
// - Added re-logging of environment info on each retry to track page load progress
// Changelog v1.2:
// - Added comprehensive debugging information to help diagnose user issues
// - Added URL detection and page structure analysis
// - Enhanced logging for DOM element discovery
// - Added language/locale detection
// Changelog v1.1:
// - Fixed browser hanging issue by adding throttling mechanism
// - Improved MutationObserver to be more selective and prevent infinite loops
// - Enhanced DOM selectors with multiple fallbacks for different Outlook versions
// - Reduced polling frequency to improve performance
// - Added better pattern matching for inbox count extraction
