Nouvelle version fraîchement sortie pour Mozilla Firefox. Pour la v49.0, le navigateur s'améliore au niveau des performances : réactivité sur MacOS et performances vidéo pour les PC sans accélération matérielle. D'ailleurs, la navigateur demande la présence des instructions SSE2 sur Windows, ce qui devrait reléguer les PC de plus de 15 ans à la version précédente.
Le mode lecture peut désormais lire à haute voix, et son mode d'impression est amélioré. En ce qui concerne la catégorie sociale, Firefox Hello est abandonné.
Voici la liste complète des modifications par rapport à la version précédente :
