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. This feature is enabled by storage API.

When a website has storage API, Firefox will first ask you for permission to let a website add files to your local storage.

When the prompt appears in your address bar, choose “Allow” or “Don’t Allow”.
