How to Bring Back “http://” in Firefox 7

Firefox 7 is out now, bringing with it much-welcome memory usage reductions and speed improvements. It has one annoying UI change, though: URLs in the address bar no longer have the “http://” protocol prefix. While that may be okay for casual users, it will annoy a lot of power users.

To fix it, just follow these steps:

  1. Open a new tab and type about:config into the address bar.
  2. Search for browser.urlbar.trimURLs
  3. Double click on the browser.urlbar.trimURLs key to change its boolean value from true to false.
  4. Close the tab and enjoy your unhidden URL protocols.

This is the second time in two versions Mozilla has made an unhelpful UI tweak. In Firefox 6 they added “domain highlighting,” which greys-out the URL text, while leaving the domain in darker lettering. Fortunately, it was just as easy to fix.
