Firefox 7 has this annoying feature to hide the http:// in front of an address and to hide a single trailing forward slash. What's most annoying, is that when copying the url to a clipboard, it prepends the http:// again. So when I enter a website, then copy the domainname to a console in order to ping/trace/whois it, I have to remove the http:// manually.
To restore the prefix, enter the url about:config. Search for browser.urlbar.trimURLs and toggle it to false. That's all folks.
