21 /** Test for Bug 795134 **/
22
23 /*
24 * This test will check that localStorage data are correctly deleted when it is
25 * requested that a mozbrowser private data are deleted.
26 *
27 * Here is the big picture of what the test does:
28 * 1. Setup permissions and preferences.
29 * 2. Install a dummy application and embed it in an iframe.
30 * 3. Load a mozbrowser iframe from this application.
31 * 4. Fill storages for the app and the mozbrowser iframe.
32 * 5. Uninstall the application.
33 *
34 * Expected result: all localStorage data from the mozbrowser have been deleted
35 * but sessionStorage stays untouched such as all non-browser data.
36 *
37 * This test is asynchronous and methods are called in a reading order.
38 * Each method has a deeper explanation of what it does
