debian 7自带的iceweasel为17.很多插件不兼容。安装firefox，需要先删除iceweasel，而iceweasel依赖gnome-core。因为要用debian stable，所以用了chrome。和手机上的chrome同步也方便。apt中的chrome，很老，bug多。下载deb包安装
$ wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
$ sudo apt-get install libgconf2-4 libnss3-1d libxss1
$ sudo dpkg -i google-chrome-stable_current_amd64.deb
$ sudo apt-get -f install
$ sudo apt-get remove iceweasel
