Mozilla Firefox 57.0.4

Une nouvelle version du navigateur Firefox vient de sortir. Au menu des nouveautés, cette version va déjà chambouler toute la gestion des extensions. En effet, Exit les anciennes extensions, bonjour les WebExtensions qui seront désormais les seules à être supportés sur Firefox. Cela permettra dans un premier temps de s'affranchir des problèmes de gestion mémoire d’antan.

Ensuite, une amélioration des performances brutes a été opéré sur le navigateur avec l'inclusion de plus en plus de bouts de code du projet Quantum qui vise à terme de supprimer le langage d'origine du navigateur, alias XUL, par le langage Rust considéré comme plus rapide.

Et pour terminer, un nouveau thème appelé "Photon" prend la place d'Australis inauguré à l'époque de Firefox 29.0.

Voici la liste complète des modifications par rapport à la version précédente :

Nouveautés de Firefox 57.0 (13/11/2017)

  • Firefox now supports only extensions built using the WebExtension API, and will deactivate unsupported legacy extensions. Learn more about our efforts to improve the performance and security of extensions
  • The browser's autoscroll feature now uses asynchronous scrolling, similar to other input methods like mousewheel, providing a smoother scrolling experience
  • The content process now has a stricter security sandbox that blocks filesystem reading and writing on Linux systems
  • Middle mouse paste in the content area no longer navigates to URLs by default on Unix systems
  • Some older versions of the ATOK IME, including ATOK 2006, 2008, 2009 and 2010, can cause crashes and are therefore disabled on the Windows 64-bit version of Firefox Quantum. To fix those incompatibility issues, please use a newer version of ATOK or one of other IMEs.

  • Complete visual refresh of both the Light and Dark DevTools themes, matching the new visual style of Firefox Quantum
