问题
Just installed geckodriver 0.16.1 and updated firefox to 53 (64bit) and my script appears like it is not setting preferences. Here is the code I use set Firefox profile so it automatically downloads a ms word file without the download prompt.
from selenium import webdriver
import os
fp = webdriver.FirefoxProfile()
fp.set_preference("browser.download.folderList", 2)
fp.set_preference("browser.download.dir", os.getcwd())
fp.set_preference("browser.download.manager.showWhenStarting", False)
fp.set_preference("browser.helperApps.neverAsk.openFile", "application/msword")
fp.set_preference("browser.helperApps.neverAsk.saveToDisk", "application/msword")
driver = webdriver.Firefox(firefox_profile=fp)
This script worked before updating Firefox and geckodriver. Now when I run it, the download prompt appears.
Anyone having similar issues or know what changed with geckodriver?
回答1:
These preferences have changed in newer firefox versions. Go to about:config in firefox and search for browser.download, it will show you what the newer ones are. For instance, browser.download.dir would now be browser.download.lastDir
