Clear Cookies in Firefox

Cookies consist of various bits of information that websites store on your computer. These pieces of information can make your browsing experience more convenient since they store website preferences and login statuses, but sometimes cookies slow your computer down or cause problems. You can clear the cookies previously stored on your computer and you can also block future cookies. Here's how to do it if Firefox is your default browser.

Steps

1. Click on the "Firefox" button. The "Firefox" button is located in the upper left corner of the Firefox browser window.
   • Clicking on this button will open a drop-down menu with two columns.

   • Once you click on "Options" in the "Options" sub-menu, a separate dialogue box will pop up.
   • Note that "Options" only applies to PC users. Mac users will need to click on "Preferences," but the remaining steps are the same.
3. Switch to the "Privacy" panel. The "Privacy" panel icon is located along the top of the "Options" dialogue box.
   • Each panel icon is labeled and accompanied by a corresponding graphic. "Privacy" is the fifth icon and its graphic icon looks like a masquerade mask.
