錯誤：使用firefox禁用watir上的圖像加載

Question

我通過更改watir-webdriver的配置文件出錯了。 我使用以下代碼禁用在Firefox中加載圖像：

profile = Selenium::WebDriver::Firefox::Profile.from_name "default"
profile['permissions.default.image'] = 2
browser = Watir::Browser.new :firefox, :profile => profile

出現此錯誤消息：

/var/lib/gems/2.3.0/gems/selenium-webdriver-3.0.0/lib/selenium/webdriver/remote/w3c_bridge.rb:80:in `initialize': unknown option: {:profile=>#<Selenium::WebDriver::Firefox::Profile:0x00000000e90700 @model="/home/amvisor/.mozilla/firefox/9ud9suhs.default", @native_events=false, @secure_ssl=false, @untrusted_issuer=true, @load_no_focus_lib=false, @additional_prefs={"permissions.default.image"=>2}, @extensions={}>} (ArgumentError)

        from xxx.rb:38:in `new'
        from xxx.rb:38:in `<main>'

什么意思：

initialize: unknown option: {:Profile

有人可以幫忙嗎？ 謝謝！

Answer 1

這適用於使用Firefox 48+的現有Firefox配置文件：

profile = Selenium::WebDriver::Zipper.zip('/path/to/profile/xxx.default')
caps = Remote::Capabilities.firefox(firefox_options: {profile: profile})
browser = Watir::Browser.new :firefox, desired_capabilities: caps

Ruby綁定尚未完全支持新geckodriver中舊版Firefox驅動程序的Firefox配置文件的所有功能。 如果您需要這些附加功能，可以使用Firefox <48（我建議安裝擴展支持版本）並傳遞marionette: false功能。
