Selenium:Firefox Webdriver的about:config中的布尔设置 [英] Selenium: boolean setting in about:config of Firefox webdriver

问题描述

对于一个测试套件，我正在运行一个使用selenium webdriver控制Firefox实例的python脚本.我想将about:config中的设置dom.disable_open_during_load更改为true.尽管这是默认Firefox配置文件中的默认设置，但是每当我启动Webdriver实例时，selenium都会将其更改为false(用户定义).似乎使用的是匿名的，略有更改的个人资料?！然后，我可以手动将其改回，但是我却在用代码来解决这一问题:既不使用新的配置文件，也不使用通过Firefox的配置文件管理器配置的预设配置文件即可解决此问题.

For a test suite, I'm running a python script controlling a Firefox instance using selenium webdriver. I want to change the setting dom.disable_open_during_load in about:config to true. Although this is the default setting in my default Firefox profile, selenium changes it to false (user-defined) whenever I'm starting a webdriver instance. It seems to use an anonymous, slightly changed profile?! I can then manually change it back, but I was struggling to do it with code: neither using a new profile nor using a pre-set profile configured with Firefox' profile manager solves the problem.

from selenium import webdriver

FFprofile = webdriver.FirefoxProfile()
FFprofile.set_preference('dom.disable_open_during_load', 'true')  # I also tried True, 1 - with and without quotes
# FFprofile = webdriver.FirefoxProfile('C:/Users/ExampleUser/AppData/Local/Mozilla/Firefox/Profiles/owieroiuysd.testprofile')


FFdriver = webdriver.Firefox(firefox_profile=FFprofile)
FFdriver.get('http://www.google.com')

我可以通过这种方式更改各种设置，但不适用于此设置.更改后的值false用户定义"来自何处?它是硒自动设置的地方吗?我正在使用:

I can change various settings this way, but it doesn't work for this one. Where does the changed value false "user-defined" come from? Is it an automatic setting of selenium somewhere? I'm using:

• geckodriver 0.16.1
• 硒3.4.2.
• Firefox 53.0.3(64位)
• python 3.4.4

编辑:我刚刚发现

I just found this question on SO, dealing with the same problem in java.

如果事实证明这是不可能的，那么可能有一个不错的解决方法?有什么想法吗?

If this turns out to be impossible, probably there is a nice work-around? Any ideas?

推荐答案

fp = webdriver.FirefoxProfile()
fp.DEFAULT_PREFERENCES['frozen']["dom.disable_open_during_load"] = True

请勿使用profile.set_preference('dom.disable_open_during_load', True)，因为profile.default_preference将被冻结的覆盖.

Don't use profile.set_preference('dom.disable_open_during_load', True) as profile.default_preference will be overrided by frozen's.
