User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:22.0) Gecko/20100101 Firefox/22.0 (Beta/Release) Build ID: 20130627185035 Steps to reproduce: to reproduce I went to http://google.com Actual results: in the location bar, only "www.google.com/" was shown. Expected results: The whole "http://www.google.com/" should be shown, rather than only part of the address.

This is correct by design. If you want to see the full address, you can go to about:config and change browser.urlbar.trimURLs to false.

Trimmed URL, nothing new or buggy.

But then why does it not hide the url if it says https://? That is inconsistent to hide one but not the other.

Only HTTP is trimmed, HTTPS is not due to security reasons for the user.

That still doesn't answer the question of why it is being trimmed in the first place. If the https is shown for security reasons, then wouldn't you want the user to know when they are NOT on a secure page by showing the http?

Because by default, the protocol is HTTP and it's unsecure, so it's redundant to display it. Secure pages are identified with the padlock, see https://support.mozilla.org/en-US/kb/how-do-i-tell-if-my-connection-is-secure Other protocols are displayed normally.

Because a bigger difference (the lack of https where it should be) is easier to notice.
