MCP Bridge for Claude.ai - Firefox Release Notes (v1.0.2)
================================================================================

WHAT'S NEW

Auto-Connect on Page Load

• Enabled MCP servers now connect automatically when you open Claude.ai
• No more manual toggling required after a page refresh
• Tools appear in Claude.ai as soon as the connection is ready

Reliable Tool Injection

• Fixed race condition where tools failed to appear in Claude.ai on the
  first page load despite the server connecting successfully
• Extension now waits for Claude.ai's UI to fully mount before handing
  off the connection, preventing missed messages
• Toggling a server off in Manager now immediately disconnects it from
  Claude.ai without requiring a page refresh

Manager Page Cleanup

• Manager page now properly disconnects all active connections when
  the tab is closed, preventing orphaned background connections

BUG FIXES

• Fixed disabled servers occasionally still attempting to connect
• Fixed server config sent to page context could include raw unsanitized
  server data on storage changes (now always sanitized via allowlist)
• Fixed connection resource leaks: port1 channels, pending request Maps,
  and warning timeouts are now properly cleaned up on disconnect
• Fixed concurrent syncConnections() calls causing race conditions when
  toggling servers rapidly (mutex guard added)
• Fixed disconnect() being unsafe to call multiple times (idempotency guard)
• Fixed stale "Claude.ai hasn't responded" warnings firing after a server
  was already disabled
