On Firefox, the empty space that appears on either side of the address bar is known as “Flexible Space,” which allows you to add extra space to separate groups of items, or to center or make the address and search bar smaller by adding multiple flexible spaces.
If you want to add or remove empty space in the toolbar, it’s a very easy task on Firefox.
In this guide, you’ll learn the steps to manage Flexible Space on Mozilla’s Firefox web browser on Windows 10, but the same instructions will work with other OSes.
