如何修改 chrome 的預設參數，資料來源：

解法：
There is a file called “Preferences” within the “User Data/<Profile>” folder that appears to contain these settings. The location of this file varies according to OS. For the “Default” profile this is located at:
WinXP:
C:\Documents and Settings\<User Name>\Local Settings\Application Data\Google\Chrome\User Data\Default\Preferences
WinVista:
C:\Users\<User Name>\AppData\Local\Google\Chrome\User Data\Default\Preferences
You then need to search for the appropriate setting in that file. I would close Chrome (and backup) first as this file appears to be updated automatically as you navigate tabs.
“Enable Auto-fill to fill in web forms in a single click.” appears to be stored here:
"autofill": {
"enabled": true,
“Offer to save passwords I enter on the web.“
"password_manager_enabled": true,Deploy initial preferences:

寫入 Preferences 的程式碼：
def nodriver_overwrite_prefs(conf, prefs_dict={}):
prefs_filepath = os.path.join(conf.user_data_dir,"Default")
if not os.path.exists(prefs_filepath):
os.mkdir(prefs_filepath)
prefs_filepath = os.path.join(prefs_filepath,"Preferences")
prefs_dict["profile"]={}
prefs_dict["profile"]["name"]=CONST_APP_VERSION
prefs_dict["profile"]["password_manager_enabled"]=False
json_str = json.dumps(prefs_dict)
with open(prefs_filepath, 'w') as outfile:
outfile.write(json_str)
