FF 39. Linux. Периодически крашится.

Добрый день.
После обновления FF до версии 39 сразу же начались рандомные вылеты браузера. Может произойти при просмотре вэб страницы, иногда при закрытии браузера выскакиевает окно о краше.
Пробовал запустить на чистом профиле - результат тот же. Так что скорее всего дело не в разширениях.

Частые вылеты серьезно раздражают. Помогите советом где искать причину?

Вывод терминала при запуске и краше FF на моем основном профиле:

вывод
