firefox start in offline mode

   今天发现firefox居然以offline启动了,虽然每次都可以手动改为online,可这总不是办法.想想应该是firefox和network关联了什么东东,每次发现不能连接外网时就设置firefox为offline.
   google了一把.
   In many modern Linux distributions network management is controlled by the user-friendly NetworkManager utility. Sometimes there is a bit of a disconnect between Firefox and NetworkManager.? This doesn’t happen often (Most often this happens in Fedora.), but when it does happen it will make you feel like you have no idea what you are doing.

There are two ways to get around this. The first way is go hop on to Firefox, open the about:config window (you will most likely have to click the check box promising you’ll be careful using this configuration page), and do a search for the string:

toolkit.networkmanager.disble

By default this is set to false which means it is working in conjunction with NetworkManager to see if there is a connection. Set this string to true, restart Firefox, and you most likely will not have this problem again.
