Do you have any hint to give me to solve this problem ?

Answer 1

The firefox binary path that needs to be passed in FirefoxBinary('') should be the path for the executable 'firefox.exe'.
E.g.:
ff_binary = FirefoxBinary("C:\\Program Files (x86)\\Mozilla Firefox\\firefox.exe")
driver = webdriver.Firefox(firefox_binary=ff_binary)
PS: In your case, the path you've specified is the path where the firefox profile is stored normally.
Hope this helps.
