Proper Menubar works right out of the box; just install it and you’ll see the black Google menu bar back up top, as if it never left. You’ll also see a new icon added to your browser toolbar; right-click on Proper Menubar’s icon and go to “Options.” Here, you can customize the look of the menu bar (color of links, background color), as well as the items you want displayed in the menu bar.
Plus, you can choose which websites to display the menu bar on (ie. Google websites only, all websites, a specific website). You can also use the browser toolbar icon to hide/show the menu bar as you’d like. This extension does not hide the App Launcher, but you no longer have to use it if you you don’t want to. If you like to see all of your links at a glance, rather than hidden behind icons, this is a great extension to use.
