The Toolbars

The first thing to know about Firefox's toolbars is that you can customize them any way you want. With a drag and drop it is easy. In the picture you can see that you can put a check mark before the words Navigation Toolbar and Bookmark Toolbar. The Navigation Toolbar is the one that has the back and forward button on it along with the address box. The Bookmarks toolbar is the bar underneath the Navigation Toolbar it's simular to the links bar in IE. Whatever bookmarks you have in the bookmarks folder "Bookmarks Toolbar Folder" will be in the Bookmarks Toolbar.
When you pick customize a big box will pop up and you can drag anything to and from it. You can even drag the bookmark toobar items to the top menubar if you like and then uncheck the the Bookmark Toolbar so you will have more room to see the webpage you are looking at.

Just go here on the menu bar.

You will be able to drag and drop from toolbars.

Click and hold down to drag

My personal preferences are to pull new tab button to the left of the address bar, that way if I want a new tab I just hit the button and start typing an address. I also like to pull the Bookmark Toolbar Items to the top bar and hide the Bookmarks Toolbar so I can see more of the webpage. I'm always using google(I know I can put it on the toolbar but I like using the page) and a dictionary page so I put them in the Bookmarks Toolbar folder then a link is always displayed at the top for quick access. In the pic it shows how to do that. You go to Bookmarks > Bookmark this page to get it and that's the same way you can add a bookmark to any other bookmark folder.

In this folder, the link will on the Toolbar

Under the Bookmarks Toolbar will be the Tab Bar if you have more than 1 tab open. Don't confuse the 2, to a new person they can look the same. The Tab Bar looks like tabs in a file cabinet, thats where they got the name(I think). The next page is about Tab Browsing, we'll go over a lot of things you can do with tabs instead of opening new windows all the time.
