In the new tab bar design, you should still find a "+" button to open a new tab just after the last tab, but depending on your color scheme, it may be harder to spot. Can you see it there, or does it appear if you mouse over that area?

The Ctrl+t keyboard shortcut also should work.

If you were clicking something else, could you describe it in a little more detail?

Thanks; its on my office computer and I won't be there until Friday but I will let you know! For some reason I don't have the same problem on my laptop with the new version of Firefox.

I tried moving the cursor next to the tab, where the + sign should be indicating that I can open a new tab, but to no avail. I do appreciate the tip of control T and that helps. But it would be great to just have the + sign appear next to an open tab the way it does on my laptop.

Its possible that it was moved, or removed.

Move your mouse to the top of the Firefox window, then right click. You will see a menu of the available toolbars. Select Customize. In the new window, look for the icon. When you find it, hold down the left button on it, and move it to where you want it to be. You can move any of the icons you want from here, but some icons are locked in place.

Use Toolbar Layout (Customize) to open the Customize window and set which toolbar items to display.

• if missing items are in the Customize palette then drag them back from the Customize window on the toolbar
• if you do not see an item on a toolbar and in the Customize palette then click the "Restore Defaults" button to restore the default toolbar setup
