I think full urls are an extremely important feature to have in order to prevent hacking by phony websites. The difference between http and https is significant.
So Firefox 7 (newest release) decided it isn’t. How to change the browser’s mind about that?
Most know the “about” feature in Firefox. It’s been around forever, and allows you to change features in the browser.
So… you want full url’s back? Here’s how:
1. In Firefox's URL bar, type in: about:config and agree to the pop-up message (don’t worry about a “guarantee”).
2. Search for: browser.urlbar.trimURLs by just scrolling down the long list.
3. Double-click or right-click and select "toggle" to change the value to “false”.
You'll get the full HTTPS or HTTP in the URL so you won't be confused on whether you're viewing a secure site.
