在 selenium 下启动的浏览器不使用插件

Question

我正在使用 python+selenium，配置文件有插件。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，它可以工作。

这是打印到日志中的内容。

难道是因为这些错误？

代码本身根本没有意义：

#!/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：

火狐浏览器 68.9.0esr

壁虎驱动程序 0.26.0 (e9783a644016 2019-10-10 13:38 +0000)

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。但是这里有那个配置文件

在您的配置文件中有一个文件：prefs.js其中包含一行user_pref("extensions.lastAppBuildId", "20200707180101");对于禁用的插件，该行可能有问题。因此，您可以测试将此数字减 1 或删除整行（未经测试）。profile.set_preference("extensions.lastAppBuildId", "<apppID> -1 ")完整示例代码：from selenium.webdriver import FirefoxProfilefrom selenium import webdriverpath = '%APPDATA%\Mozilla\Firefox\Profiles\azk4wioue.default' #path to your profileprofile = FirefoxProfile(path)&nbsp;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')&nbsp;driver = webdriver.Firefox(firefox_profile=profile)或者通过临时配置文件在每次运行时安装干净的插件。# 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，您可以尝试以这种方式设置扩展名：from selenium.webdriver import FirefoxProfilefrom selenium import webdriverprofile = 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，您也可以尝试以下操作：def newTab(fx, url="about:blank"):&nbsp; &nbsp; wnd = fx.execute(selenium.webdriver.common.action_chains.Command.NEW_WINDOW)&nbsp; &nbsp; handle = wnd["value"]["handle"]&nbsp; &nbsp; fx.switch_to.window(handle)&nbsp; &nbsp; fx.get(url) # changes handle&nbsp; &nbsp; return fx.current_window_handledef retoggleAllTheAddons(fx):&nbsp; &nbsp; initialHandlesCount = len(fx.window_handles)&nbsp; &nbsp; addonsTabHandle = newTab(fx, "about:addons")&nbsp; &nbsp; fx.execute_script("""&nbsp; &nbsp; &nbsp; &nbsp; let hb = document.getElementById("html-view-browser");&nbsp; &nbsp; &nbsp; &nbsp; let al = hb.contentWindow.window.document.getElementsByTagName("addon-list")[0];&nbsp; &nbsp; &nbsp; &nbsp; let cards = al.getElementsByTagName("addon-card");&nbsp; &nbsp; &nbsp; &nbsp; for(let card of cards){&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; card.addon.disable();&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; card.addon.enable();&nbsp; &nbsp; &nbsp; &nbsp; }&nbsp; &nbsp; """)&nbsp; &nbsp; if len(fx.window_handles) != 1:&nbsp; &nbsp; &nbsp; &nbsp; fx.switch_to.window(addonsTabHandle)&nbsp; &nbsp; &nbsp; &nbsp; fx.close()
