Current Firefox versions use a combined Stop/Reload/Go button that is positioned at the right end of the location bar.

• During the page load process it shows as a Stop button and after the loading has finished the button is changed to a Reload button.
• If you type in the location bar then that button becomes a Go button.

Make sure that toolbars like the "Navigation Toolbar" and the "Bookmarks Toolbar" are visible.

• Firefox menu button > Options
• View > Toolbars (press F10 to display the menu bar)
• right-click empty toolbar area

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

• check that "Bookmarks Toolbar items" is on the Bookmarks Toolbar

• if missing items are in the toolbar 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 toolbar palette then click the "Restore Default Set" button to restore the default toolbar set up

I had same problem, selected VIEW, TOOLBARS and then CUSTOMISE and discovered the REFRESH had somehow become hidden beneath some other buttons. I dragged and dropped them back into place!

Hope this helps!

The answer has already been given but it would be so much more helpful if someone had mentioned what the reload button looks like. It is a circle with an arrowhead on it at the one o'clock position - sorry but I don't have the skill to reproduce it here.

It is located at the far right end of the navigation toolbar. That is the toolbar where you type in ( on the left side) the information of a site you want to visit such as www.answers.com.

The replies are further obfuscated by information on customizing toolbars - You should not need to do any of this. I suspect that everyone already has the navigation bar in place.
