PROBLEM: The URL in the address bar does not show HTTP, but when I copy, it copies HTTP.
SOLUTION: Type about:config in the address bar and press enter to agree to the warning. Search for browser.urlbar.trimURLs. Double click it to change it to false.
WHY: Probably aesthetics.
NOTE: Your browser will ALWAYS show HTTPS regardless of this setting. Messing around with about:config can seriously damage your browser. Do this only if you know what you are doing or can follow instructions.
