Clear Firefox history and cache

You may need to have a private moment in Firefox browser, especially in library or other public computers. You can clear Firefox history for your browsing.

At the top of the Firefox window, click the Firefox button, go over to the History menu and select Clear Recent History. You can select clear history in this hour, today or  all.

To clear Firefox cache, go to Options->advanced and click clear now button.

Another way is to use to "start private browsing" button in Firefox, then you do not need to clear Firefox history.
