已将 Firefox 更新至版本 48，但出现以下错误。任何帮助如何解决它:

Selenium::WebDriver::Error::WebDriverError: unable to obtain stable firefox connection in 60 seconds (127.0.0.1:7055) from /Library/Ruby/Gems/2.0.0/gems/selenium-webdriver-2.52.0/lib/selenium/webdriver/firefox/launcher.rb:90:in connect_until_stable' from /Library/Ruby/Gems/2.0.0/gems/selenium-webdriver-2.52.0/lib/selenium/webdriver/firefox/launcher.rb:55:inblock in launch' from /Library/Ruby/Gems/2.0.0/gems/selenium-webdriver-2.52.0/lib/selenium/webdriver/common/socket_lock.rb:43:in locked' from /Library/Ruby/Gems/2.0.0/gems/selenium-webdriver-2.52.0/lib/selenium/webdriver/firefox/launcher.rb:51:inlaunch' from /Library/Ruby/Gems/2.0.0/gems/selenium-webdriver-2.52.0/lib/selenium/webdriver/firefox/bridge.rb:43:in initialize' from /Library/Ruby/Gems/2.0.0/gems/selenium-webdriver-2.52.0/lib/selenium/webdriver/common/driver.rb:53:innew' from /Library/Ruby/Gems/2.0.0/gems/selenium-webdriver-2.52.0/lib/selenium/webdriver/common/driver.rb:53:in for' from /Library/Ruby/Gems/2.0.0/gems/selenium-webdriver-2.52.0/lib/selenium/webdriver.rb:86:infor' from /Library/Ruby/Gems/2.0.0/gems/capybara-2.6.2/lib/capybara/selenium/driver.rb:13:in browser' from /Library/Ruby/Gems/2.0.0/gems/capybara-2.6.2/lib/capybara/selenium/driver.rb:45:invisit' from /Library/Ruby/Gems/2.0.0/gems/capybara-2.6.2/lib/capybara/session.rb:232:in visit' from /Library/Ruby/Gems/2.0.0/gems/capybara-2.6.2/lib/capybara/dsl.rb:51:inblock (2 levels) in ' from /Users/mesutgunes/scripts/capybara.rb:53 from /usr/bin/irb:12:in `'

没有 selenium-webdriver v3 和 geckodriver，Firefox v48 无法使用(在 Capybara 中)。 selenium-webdriver v3 有一个测试版，但它目前缺少许多关键功能(例如无法读取表单元素的当前值)，并且尚未真正准备好用于实际测试使用。目前降级至47。
