Connexion non sécurisée sur certains sites

Bonjour,

J'ai des connexions non sécurisées sur certains sites (cçm, fnac, allociné,...), mais pas sur d'autres (france inter,...).

J'utilise mozilla.

Si j'utilise d'autres navigateurs, c'est aléatoire.

Si quelqu'un a une idée...

Voici le scan d'adw cleaner :
