Application Cache storage has been removed in Nightly and early Beta

Published: | Categories: HTML


The browser storage for HTML5 Application Cache (AppCache), deprecated since Firefox 44, is no longer available in the Nightly and early Beta/DevEdition channels starting with Firefox 71. It will be removed from all channels after a few releases. The applicationCache property and OfflineResourceList interface are still exposed on window, but the API will also be removed in the near future. The Service Worker API should be used instead.
