Summary
Firefox 154.0 is now available, adding a "Manage AI" quick action that opens the browser's AI settings directly from the address bar.
The release also changes core browser behavior: hard reloads now clear or refresh cached favicons, and Local Access Network protections now extend to WebSocket connections.
Mozilla added cross-platform profile recovery, letting backed-up local profiles on macOS be restored on Windows, macOS, or Linux, alongside Android updates and vertical tab enhancements.
Developer-facing changes in 154 include several WebDriver improvements, support for the sandbox manifest key, and new experimental web features detailed in MDN and beta release notes.
