To check and see if your bookmarks bar is showing, look under the address bar. Do you have a bar there with some links on it? If so, your bookmarks bar is on. If not, it is off.

If your bookmarks bar is off, you can turn it on with just a few clicks. Click on the hotdog menu (with the three horizontal lines) in the upper right hand corner of your screen. Choose "Bookmarks" from the menu and then choose "Show Bookmarks Bar" in the second menu. Your bookmarks bar will now appear. You can also use the keyboard shortcut to toggle the bookmarks bar off and on, which is Control+Shift+B on a PC and Command+Shift+B on a Mac.
To add a bookmark to your bar, browse to the site that you'd like to add. Then look at the address bar and click on the star you see on the far right hand side. A box will pop up so that you can name your bookmark and then click "Done" at the bottom.
Your bookmark will now show up on your bookmarks bar.
If you'd like to edit the title of your bookmarks, you can do so easily. Right click on the bookmark you wish to edit, and then click "edit" from the menu.
You can now change the name to whatever you'd like it to be and then press "Save" at the bottom of the window. Shorter is better because it will take up less space, allowing you to fit more bookmarks on the bar.
If the icons are distinct enough, like Google Drive, Gmail, Twitter, Google+, etc., you can delete the name altogether and just have the icon on the bar. Edit the bookmark the same way you change the name, except you delete all the text in the "Name" box and then click "Save" at the bottom.
Deleting the names saves so much space, and I personally think it is easier on the eye.
