Enables extensions to clear the data that is accumulated while the user is browsing.

In the browsingData API, browsing data is divided into types:

  • browser cache
  • cookies
  • downloads
  • history
  • local storage
  • plugin data
  • saved form data
  • saved passwords

You can use the browsingData.remove() function to remove any combination of these types. There are also dedicated functions to remove each particular type of data, such as removePasswords(), removeHistory() and so on.

All the browsingData.remove[X]() functions take a browsingData.RemovalOptions object, which you can use to control two further aspects of data removal:

  • how far back in time to remove data
  • whether to remove data only from normal web pages, or also from hosted web apps and add-ons. Note that this option is not yet supported in Firefox.

Finally, this API gives you a browsingData.settings() function that gives you the current value of the settings for the browser's built-in "Clear History" feature.

To use this API you must have the "browsingData" API permission.
