Linux 3.16.1-1-apparmor x86_64 的Archlinux
selenium-server 2.44.0; FF 35.0
bundle exec cucumber features/ -p firefox

如果我只是跑FF：
# firefox -v
(process:6367): GLib-CRITICAL **: g_slice_set_config: assertion 'sys_page_size == 0' failed
Mozilla Firefox 35.0
浏览器通过vnc服务器运行。
答案 0 :(得分：0)
Selenium WebDriver 2.44.0尚未支持FF35。 （见https://code.google.com/p/selenium/source/browse/java/CHANGELOG）
尝试降级你的FF以获得全面的支持。
