How to use the Firefox Forget button
Mozilla released a special version of their Firefox web browser to celebrate its 10th Anniversary. As part of the special release, a Firefox Forget button, was introduced in a set of features that help put you in more control of your privacy. The Forget button allows you to easily clear out some of your recent browsing history in a single click right from an icon in your toolbar. This is particularly useful for users who share a computer, and wish to quickly and easily purge their browsing history when done surfing. Rather than offering to clear the full array of stored History, the Forget button will close all tabs and windows, delete recent cookies, delete recent history, and open a new, clean window for the next user.
To use the Firefox Forget button, first add it to the toolbar area. Here’s how:
1. Click the Menu button 
in the upper right corner of Firefox, and click 
at the base of the window.
2. A new Customize Firefox tab will open. Under Additional Tools and Features, locate the Forget icon 
.
3. Left-click and hold your mouse cursor over the Forget icon , and drag the icon to your toolbar.
4. Once you have positioned the Forget button where you want it, click 
.
5. To use the Forget feature, click the Forget button you positioned in the toolbar. A new window will display. Select whether you want to forget the last five minutes, two hours or 24 hours, then click 
. Warning: Once you have clicked , your cookies and history from within the time frame you selected are permanently deleted, and the action cannot be undone.
When Firefox has completed clearing the cookies and history, all of your open tabs and windows will be closed, and a new, clean window will launch. So, next time you forget to open a New Private Window in Firefox on a shared computer, don’t forget to Forget instead!
