When I select View/Toolbars both Menu and Navigation bar are selected, but I do not have the menu bar that has the refresh button, home button, etc. All post that I see on this issue are telling you to check these two menu bars. I have them selected, but still do not have the menu I used to have and still desire.

Firefox 4.0 has a combined Reload, Stop, & Go button that appears at the right end of the Location bar, which is part of the Navigation Bar. Only one function is ever active at any one time, so combining them save UI space was a good idea. When a page is loading, it is a "Stop" button, when it finished loading, it turns into a "Reload" button, and when you start to type something into the Location bar it turns into a "Go" button.

To restore the Firefox 3 appearance you can use these steps:

• Open the "View > Toolbars > Customize" window or right-click a vacant area on a Toolbar, except fot the Bookmarks Toolbar.
• Then drag'n'drop the Reload and Stop buttons to their previous position at the left side of the Location bar.

1. Set the order to "Reload - Stop" to get a combined "Reload/Stop" button.
2. Set the order to "Stop - Reload" to separate them and get two distinct buttons.

The Home button was moved to the extreme right-side of the Navigation Bar. It can be moved to where you want it while in the Customize node, too.
