Twitter connect does not work in localhost?

The twitter app does not accept http://localhost/joomla25 as a valid URL in its Website field.

I´m developing on a local computer and CB connect worked perfectly for facebook but twitter keeps on saying something went wrong when I try to use my twitter account to login.
I tried using different placeholders but still it didn´t work.

Any suggestions, of course I could set up a developing environment on a real server but I don´t want to do it yet.

Most connect sites don't accept localhost. You need to make your localhost accessible to the internet and use your IP address.
