I guess some people are still attached to the search bar in the upper right corner of the browser. Since Chrome, I quickly got used to never having it and simply typing my searches directly into the address bar. In Firefox, you can do the same thing, but by default the search stays in that upper right corner. Here’s how to quickly remove it.
1) Right click on the navigation panel, select Customize.
2) Drag the Search component to the new window that opened up.
Easy!
