Mozilla's newly released Firefox 155 browser introduces multiple new features, with a focus on enhancing web connection speeds. It supports the Happy Eyeballs v3 and QUIC v2 protocols to optimize connection paths, and introduces an optional AI-driven desktop browsing window, Smart Window (currently available only to users in the United States, Canada, and France). Additionally, the new version fixes an issue where Linux systems were unable to enter sleep mode after prolonged browsing sessions, and includes updates such as WebAssembly support for developers.
