Clearing your data after browsing can be useful if you are using a shared computer. This will prevent the other users from knowing what you have been browsing. It will also keep the computer from storing any information you have input into websites, etc.

To always clear data everytime you exit out of your Mozilla Firefox browser, you need to do the following:

Open your browser window. Look at the menu bar and click on “Tools.” A drop down menu will appear and select “Options.” Click it.

Once the “Options” window is open, look for the tab that says, “Privacy.”

Click the box that is beside the option that says, “Always clear my data when I close Firefox.”

Click the “Settings” button next to this option and tick the box next to “Cookies” and you will also make sure that cookies will be automatically deleted as well.
