Version 1.4.3 Major Architectural & Reliability Update:
• Bifurcated Filter Lists: Search Engines and YouTube now have independent filter lists so YouTube creators can be filtered without interfering with regular web/image searches.
• Instant Whole-Page Blanking: Search queries matching blocked keywords render as a 100% white screen instantly with zero visual flicker.
• Surgical Domain Filtering: Blocking domains (e.g., instagram.com) only hides matching links and image tiles, preserving non-blocked content.
• 10x Faster Matching Engine: Pre-compiled entity parsing drastically speeds up DOM evaluation while scrolling.
• Reliable .txt Export: Fixed list export functionality across all tabs.

Version 1.4.2 Performance & Reliability Update:
• Blazing-Fast Performance: Re-architected DOM scanning engine for instant filtering with zero layout reflows or stutter.
• Ultra-Smooth Scrolling: Optimized MutationObserver to maintain 60fps even on infinite-scroll feeds and video pages.
• Instant Multi-Tab Sync: Updated settings apply immediately across all open tabs.
• Reduced Memory Footprint: Pre-compiled keyword matching engine drastically reduces CPU and battery consumption.

What's New in Version 1.4.1:

Smart Whole-Word Matching: Our keyword detection now uses smart RegEx word boundaries (\b) to prevent false positives (e.g., blocking "art" no longer blocks "smart"). It seamlessly falls back to exact-substring matching for non-English characters for global compatibility.
YouTube SPA Stability: We updated our YouTube page-blanking logic to target the core structural ytd-app container instead of fragile dynamic selectors, preventing filtering races during SPA navigations.
Native InPrivate Support: We added "incognito": "spanning" to the manifest. This allows the extension's background processes and storage to seamlessly bridge across standard and InPrivate windows without breaking the user's blocklist.
Permissions: No new permissions were added. We continue using local storage and our existing host permissions.
