// The profile contains two cache storages:
// - storage/default/chrome/cache,
// - storage/default/http+++www.mozilla.org/cache
// The file create_cache.js in the package was run locally, specifically it
// was temporarily added to xpcshell.ini and then executed:
// mach xpcshell-test --interactive dom/quota/test/xpcshell/create_cache.js
// Note: it only creates the directory "storage/default/chrome/cache".
// To make it become the profile in the test, two more manual steps are
// needed.
// 1. Remove the folder "storage/temporary".
// 2. Copy the content under the "storage/default/chrome" to
// "storage/default/http+++www.mozilla.org".
// 3. Manually create an asmjs folder under the
// "storage/default/http+++www.mozilla.org/".
