Firefox безголовый режим с Selenium: почему он запоминает старый доступ?

Question

Я пытаюсь создать систему для автоматизации процедуры входа на booking.com.

Что я хочу сделать sh, это когда я посещаю следующую страницу: https://join.booking.com/?lang=it, браузер должен показать мне форму входа, когда я впервые ее посещал.

К сожалению, этого не происходит, почему-то Firefox помнит, что у меня есть что-то уже сделано на этой странице и покажи мне страницу "продолжить регистрацию". Я читал, что селен всегда имеет свободный запуск sh, я отключил кеш-память, автозаполнение формы, но все равно не могу это сделать.

Есть предложения? Может быть, нужно установить какое-то предпочтение Firefox, например, кеш-память e cc ...
