Do you mean a new tab, or just you went to another page? (etc. you were on website A, and clicked on a link to website b). In that case, just hit the back button.

I have no back buttons! I have checked in file, edit, view, history, bookmarks, tools and help. If you know of another place to look let me know????

Use one of these methods to open the tab history list if you want to skip pages:

• Right click on the Back or Forward button
• Hold down the left mouse button on the enabled Back or Forward button until the list opens

snapshot10, since you aren't having a back button appear, it is probably an extension that is causing you trouble. Try starting Firefox in Safe Mode, and see if that helps.

Make sure that toolbars like the "Navigation Toolbar" and the "Bookmarks Toolbar" are visible: "View > Toolbars"

• Open the Customize window via "View > Toolbars > Customize"

• 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
