Learn about local storage, how to access storage settings, remove site data or set exceptions for websites to store data in Firefox.

Some websites have the ability to store information, such as files, in your local storage, and these files can only be removed manually by you. This helps the website run faster and prevents information from being lost if you lose your connection. Firefox shows you how much space is being used and lets you manage these settings to free up space. __TOC__ =Access site storage settings= You can access site storage settings in your Firefox settings as follows: #[[Template:optionspreferences]] #Select the {menu Privacy & Security} panel and go to the '''Cookies and Site Data''' section. ;[[Image:CookiesandSiteD]] =Delete site storage for individual websites= #In the '''Cookies and Site Data''' section, click {button Manage Data…} .
