Adding the .com and more in Firefox!
This is a weird, quite unknown feature in Firefox that will make typing website addresses in the address bar faster. It can really be useful. The way it works is that you only type the part before the ".com" and instead of pressing "Enter", you press "Command - Enter". It will automatically add the ".com". So if you write "apple" and press "Command - Enter", it will automatically direct you to apple.com! You can also do "Shift - Enter" to add ".net" or "Shift - Command - Enter" to add ".org". I unfortunately haven't found any way to do the same kind of thing in Safari or Camino!
