Hi, had already checked out that link and followed through but with no luck. However, after spending a few hours, I did find the solution.
Even though the Firefox "button" was not available/viewable, the 3.6 version option of VIEW was. Under VIEW, TOOLBARS, I unchecked the MENU Toolbar. Voila, the Firefox button suddenly appeared. All of the options on the old Menu Toolbar are covered by the Firefox Button. Now I can finally follow the new directions for personalizing my browser which all seem to start with.... "Click the Firefox Button...."
