Plantage web/actualisation soudaine

Bonjour,

J'ai un souci lorsque je navigue sur safari depuis quelque temps et je n'ai toujours pas trouvé de solution malgré mes tentatives (suppressions caches, cookies, installation d'un anti-malware).

Cela arrive généralement sur Facebook mais ça peut arriver sur d'autres pages safari, la page se "plante" et réactualise soudainement la page pour m'afficher : "Un problème est survenu avec cette page web qui a donc été actualisé".

En plus de ça, une nouvelle fenêtre s'affiche avec un grand rapport de codage comme celui ci (pas au complet) :

"Contenu web safari a quitté de manière imprévu
