1435914 - Missing functionality: Get browser cache stats and empty cache

Status: RESOLVED WONTFIX

(WebExtensions :: Untriaged, enhancement)

Description

[Jason Purdy]

Looking to upgrade my add-on Cache Status[1] and I'm not seeing WebExtension API support for querying RAM and Disk cache usage. Also not sure if there's a way to empty the cache.

My old code looked something like this:

  var cache_service = Components.classes["@mozilla.org/network/cache-service;1"].getService(Components.interfaces.nsICacheService);

Thanks!

The design of the WebExtensions API is meant to insulate and abstract the ways extensions interact with the browser. So while this was available in the old extension architecture, exposing the Firefox cache to WebExtensions runs a bit counter to its design goals.
