Bonjour,
J'ai un soucis avec Firefox 51.0.1 qui plante très régulièrement depuis qq temps.
J'ai des logs :

Il plante aussi en safe mode, mais la fréquence est beaucoup plus faible. Je n'ai pas installé d'extensions (elles sont à jour) récemment.
J'ai 16G de RAM et pas de libre. Mais dans les log, j'ai des "Out of memory".
On peut voir ce qu'il se passe dans ces logs à lui ?
J'ai activé les crashs reports, mais il n'y a rien dedans. C'est un plantage "violent" sans message, rien.
Merci
