  • Firefox Est En Train De Mourir !
    Firefox est en train de mourir ! 18/07/2018 Bonjour le Monde ! je viens d’apprendre que Firefox ne représente plus que 6% de parts de marché alors qu’il en avait 30% en 2010 ! Il est donc en train de mourir et c’est une très mauvaise nouvelle, importante et très triste car cela confirme le déclin du logiciel libre en général et donc de la faible résistance aux GAFAM et autre pilleurs de vie privée ! Ceci nous prépare d’autres scandales à la Facebook, sans compter tous ceux qui n’ont pas été révélés, que ne vont pas manquer de produire les comportements prioritairement financiers des GAFAM qui, si ils le pouvaient, écraseraient toutes les lois tendant à protéger un tant soit peu votre libre arbitre, un choix sain de concurrence et votre vie privée ! Firefox est développé par la fondation Mozilla, tout comme Thunderbird (client mail), depuis 2002 pour contrer la toute puissance d’Internet Explorer à l’époque. Il s’agit d’un navigateur moderne, performant, sûr (sécurité) et surtout respectueux de votre vie privée depuis le début de sa conception. Firefox est le navigateur par défaut des distributions Linux et ce n’est pas sans raison, mais aussi la base de toute une série d’autres navigateurs ajoutant des fonctionnalités supplémentaires souvent pour une utilisation se voulant soit plus généraliste soit de niche; on peut parler entre autres deTor , champion de la sécurité et de l’anonymat, de Cliqz, de Brave, de Cyberfox, de Waterfox, de Pale Moon (installation bloquée par Windows Defender), deK-Meleon , de Comodo Ice Dragon (celui-ci installe
