Alfred - Open selected url in browser
I've resolved the problem myself. Here is the guide :

In Alfred ( make sure you have Powerpack ), make a shellscript in extensions:

/usr/bin/open -a "/Applications/Google Chrome.app" {query}


Create an extensions in hotkeys which use our created extension with the argument is selected text in OS X.

Set your keyboard shortcut. And now, when you want to open selected url, just select the url then press your keyboard shortcut.
