Bookmark Health Master - Dead Link Cleaner & Organizer

Local-first Chrome bookmark dead link checker, 16 tech ecosystem organizer, Side Panel search & Netscape HTML backup.

Are your browser bookmarks a cluttered mess with hundreds of broken links and scattered folders? Bookmark Health Master (BHM-PRO) is a modern, privacy-first Manifest V3 browser extension built to audit, sanitize, and reorganize your native bookmark bar without forcing you to migrate to an external cloud. KEY CAPABILITIES: 1. Dual-Stage Adaptive Dead Link Prober - Runs smart HTTP HEAD probes with automatic Range-GET fallbacks to verify page reachability. - Distinguishes transient network challenges and security checkpoints from true HTTP 404/410 dead links so active websites are never falsely flagged. - Public DNS-over-HTTPS (DoH) NXDOMAIN cross-validation: Queries https://cloudflare-dns.com/dns-query solely for domain hostname existence checks, preventing false positives while keeping full URLs and query parameters completely private. - Comprehensive intranet and action shielding: Automatically bypasses private local network addresses (localhost, RFC1918 private ranges, link-local) and sensitive action paths (/logout, /unsubscribe) to protect active sessions. 2. Intelligent Domain & Ecosystem Auto-Clustering - Automatically identifies and groups scattered bookmarks into structured category folders based on domain hierarchy and platform ecosystems (cloud consoles, developer portals, AI workspaces, and productivity suites). - Collaborative Document Isolation: Separates shared online documents, spreadsheets, and wiki pages into a dedicated "Docs & Knowledge Base" directory so they never clutter your primary workspace folders. 3. Zero Data Loss Safety Engine & Move Journal - Mandatory pre-action Netscape HTML snapshot backup before any batch modification. - Quarantines broken links into a soft-delete Trash folder instead of permanently deleting them. - Move Journal: Records the original parent folder and exact slot index for every moved bookmark, allowing you to undo and restore items back to their exact original positions at any time. - 50ms serial micro-batch flow control prevents bookmark sync conflicts and node duplication. 4. Native Side Panel Companion - Built directly into the browser's native Side Panel for daily workflow efficiency. - Features category filter pills and instant keyword search to locate any bookmark in milliseconds alongside your active tabs. PRIVACY & SECURITY FIRST: - 100% Local-First: Your bookmarks, URLs, folder structures, and HTML backups remain strictly on your local device and are never uploaded to remote servers. - Hostname-Only DNS Check: Public DoH resolution sends only the isolated domain hostname to verify unreachable domains; full URLs, paths, queries, and cookies are never transmitted. - No Browsing Traffic Monitoring: The extension never monitors, collects, or alters user browsing traffic in normal tabs. Strictly during user-initiated health scans, temporary session rules remove the Origin header only on diagnostic probe requests initiated by the extension itself, and are uninstalled immediately once the scan finishes. - Credentials Omitted: All diagnostic probe requests enforce credentials: 'omit' so no cookies or session tokens are ever sent. - Minimal & Dynamic Permissions: Host permissions are never requested at installation—only optionally requested when you start a scan.
