My back button works but does not change color to show that there are pages to go back to. It would be nice if the arrow changed colors when not at the top page.

• Make sure that you have the "Navigation Toolbar" and the "Bookmarks Toolbar" visible: "View > Toolbars"
• If items are missing then see if you can find them in the "View > Toolbars > Customize" window
• If you see the missing item in the Customize window then drag it back from the Customize window onto one of the toolbars.
• If, in "View > Toolbars > Customize", you do not see that item then click the "Restore Default Set" button
