Locationbar² is a handy add-on for Firefox that does two things:

  1. It highlights the main domain name so you are 100% sure that you are surfing your bank website or PayPal and not some spoofed site designed to capture your keystrokes.
     Domain Highlight
    You can also format the appearance of domain name and other parts of the address using custom styles.
  2. Linkifies every segment of the URL in the address bar. Just hold Ctrl (to open in a new tab) or Shift (to open in a new window) or Alt (uses the current tab) and hover over the segment you want to go to and click.
     Linkification

 

In the add-on’s Options window, we can set if double clicking in the location bar will select the entire URL.

Preferences

Ticking the ‘strong’ option will bold the domain name like so:

Bold domain name

When breadcrumbs are enabled for the host, a small arrow appears right next to the main domain name.

Breadcrumb navigation for host

and when breadcrumb navigation is enabled for each segment, arrows appear after each segment.

Breadcrumb for each segment

Conclusion: All in all, Locationbar² is a very simple and handy add-on to have in Firefox. It makes navigating to different sections of a URL easy and quick. My only request to Locationbar²’s author is to provide an option to open the links (when clicked on a segment of the linkified URL in address bar) in the same tab. Currently they open in new tab always. (The author commented below that the feature exists already)
