Supprimer moteur de recherche ASK

Bonjour,

Depuis quelques temps, lorsque je fais une recherche dans la barre d'adresse, je suis redirigée vers le moteur ASK (autrefois google).
J'ai modifié la présence de ASK dans about:config et j'ai changé le moteur de recherche par defaut. Or, Ask continue de rediriger mes recherches.

Pouvez-vous m'aider je commence a m'arracher les cheveux?

Apres des recherches sur des forums, j'ai effectué des analyses. Voici les differents rapports
