Recent versions of the Firefox web browser come with a bit of whitespace on the left and right side of the browser's address bar (apparently this will launch in Firefox 57).
Some Firefox users may want to recover the whitespace to make room for the address bar or other interface elements displayed on Firefox's main toolbar.
This is important especially on low resolution devices, and if Firefox's window uses part of the screen only and not all of it.
Take a look at the following screenshot to see how the default address bar layout looks like in the web browser.
It is rather easy, thankfully, to get rid of the whitespace and recover the space in the address bar. The method requires no knowledge of CSS or editing of the userChrome.css file of Firefox.
Here is what you need to do:
The change is visible right away. You should notice that the browser's address bar is extended automatically to use the free space. It is wider now so that you see more of the URL or other elements.
You can add the whitespace to the main toolbar of the browser again at any time by dragging and dropping the "flexible space" icon to the desired location on the toolbar.
I run the Firefox window on one half of my Full HD monitor usually, as I display another browser or program in the other part at the same time. The use of whitespace in the browser's address bar led to URLs not being displayed fully which is problematic from a security, privacy and usability point of view.
Check out the following screenshot to see what I mean:
It is certainly possible to optimize the default interface to make more room for the URL part of the address bar. You can remove the whitespace, but also search if you don't use it, and move some of the functional icons on the right to the menu for example to make up more room.
Mozilla could also consider displaying only icons for containers in the browser's URL bar instead of the container icon and name if space is scarce.
Now You: How does your Firefox address bar look like? Which elements do you consider essential?
