在 selenium 下启动的浏览器不使用插件

Browser started under selenium doesn't use addons

我正在使用 python+selenium,其配置文件包含插件。 在启动时,它会暂时显示它们,但随后它们会被隐藏起来。它们存在,它们没有被禁用,但它们是隐形的并且不起作用。我可以禁用和启用它,然后它会出现在任务栏上并且可以正常工作。

使用配置文件手动调用 firefox 时,它有效。

这是打印到日志中的内容。

会不会是因为这些错误?

代码本身没有任何意义:

#!/usr/bin/env python

from selenium.webdriver import Firefox
from selenium.webdriver.firefox.options import Options

profile_path='./profile'

opts=Options()
opts.profile=profile_path
driver=Firefox(options=opts)

breakpoint()

版本可能更重要:

我正在创建一个空目录,然后 运行 firefox --new-instance --profile ./profile,然后手动将插件安装到配置文件中。但是这里有 profile

在您的个人资料中有一个文件:prefs.js,其中包含一行 user_pref("extensions.lastAppBuildId", "20200707180101"); 对于禁用的插件,此行可能有问题。因此,您可以测试将此数字减 1 或删除整行(未测试)。

profile.set_preference("extensions.lastAppBuildId", "<apppID> -1 ")

完整示例代码:

from selenium.webdriver import FirefoxProfile
from selenium import webdriver
path = '%APPDATA%\Mozilla\Firefox\Profiles\azk4wioue.default' #path to your profile
profile = FirefoxProfile(path) 
profile.set_preference("extensions.lastAppBuildId", "<apppID> -1 ")

driver = webdriver.Firefox(profile)

使用现有 firefox 配置文件的示例:

# go to the the following folder %APPDATA%\Mozilla\Firefox\Profiles\
# there the firefox profiles should be stored, the default one ending with .default
# now provide the profile to the driver like this:
profile = FirefoxProfile('%APPDATA%\Mozilla\Firefox\Profiles\azk4wioue.default') 
driver = webdriver.Firefox(firefox_profile=profile)

或者通过临时配置文件在每个 运行 上安装 addon clean。

# go to https://addons.mozilla.org and search for the plugin you want, e.g.:https://addons.mozilla.org/en-US/firefox/addon/ublock-origin/
# rightclick on the button "add to firefox"
# download the target file to a folder of your choice

# then include the addon like this:
driver.install_addon('/Users/someuser/app/extension.xpi', temporary=True)

或者 2,您可以尝试这样设置扩展名:

from selenium.webdriver import FirefoxProfile
from selenium import webdriver
profile = webdriver.FirefoxProfile()
profile.add_extension(extension='/Users/someuser/app/extension.xpi')

driver = webdriver.Firefox(profile)

如果插件在加载配置文件后存在但被禁用,您也可以试试这个:

def newTab(fx, url="about:blank"):
    wnd = fx.execute(selenium.webdriver.common.action_chains.Command.NEW_WINDOW)
    handle = wnd["value"]["handle"]
    fx.switch_to.window(handle)
    fx.get(url) # changes handle
    return fx.current_window_handle

def retoggleAllTheAddons(fx):
    initialHandlesCount = len(fx.window_handles)
    addonsTabHandle = newTab(fx, "about:addons")
    fx.execute_script("""
        let hb = document.getElementById("html-view-browser");
        let al = hb.contentWindow.window.document.getElementsByTagName("addon-list")[0];
        let cards = al.getElementsByTagName("addon-card");
        for(let card of cards){
            card.addon.disable();
            card.addon.enable();
        }
    """)
    if len(fx.window_handles) != 1:
        fx.switch_to.window(addonsTabHandle)
        fx.close()
