/*
 * Description of the Tests for
 *  - Bug 906190 - Persist "disable protection" option for Mixed Content Blocker in child tabs
 *
 * 1. Open a page from the same domain in a child tab
 *    - Load a html page which has mixed content
 *    - Doorhanger to disable protection appears - we disable it
 *    - Load a subpage from the same origin in a new tab simulating a click
 *    - Doorhanger should >> NOT << appear anymore!
 *
 * 2. Open a page from a different domain in a child tab
 *    - Load a html page which has mixed content
 *    - Doorhanger to disable protection appears - we disable it
 *    - Load a new page from a different origin in a new tab simulating a click
 *    - Doorhanger >> SHOULD << appear again!
 *
 * 3. [meta-refresh: same origin] Open a page from the same domain in a child tab
 *    - Load a html page which has mixed content
 *    - Doorhanger to disable protection appears - we disable it
 *    - Load a new page from the same origin in a new tab simulating a click
 *    - Redirect that page to another page from the same origin using meta-refresh
 *    - Doorhanger should >> NOT << appear again!
 *
 * 4. [meta-refresh: different origin] Open a page from a different domain in a child tab
 *    - Load a html page which has mixed content
 *    - Doorhanger to disable protection appears - we disable it
 *    - Load a new page from the same origin in a new tab simulating a click
 *    - Redirect that page to another page from a different origin using meta-refresh
 *    - Doorhanger >> SHOULD << appear again!
 *
 * 5. [302 redirect: same origin] Open a page from the same domain in a child tab
 *    - Load a html page which has mixed content
 *    - Doorhanger to disable protection appears - we disable it
 *    - Load a new page from the same origin in a new tab simulating a click
 *    - Redirect that page to another page from the same origin using 302 redirect
 *    - Doorhanger >> APPEARS << , but should >> NOT << appear again!
 *    - FOLLOW UP BUG 914860!
 *
 * 6. [302 redirect: different origin] Open a page from the same domain in a child tab
 *    - Load a html page which has mixed content
 *    - Doorhanger to disable protection appears - we disable it
 *    - Load a new page from the same origin in a new tab simulating a click
 *    - Redirect that page to another page from a different origin using 302 redirect
 *    - Doorhanger >> SHOULD << appear again!
 *
 * Note, for all tests we set gHttpTestRoot to use 'https' and we test both,
 *   - |CTRL-CLICK|, as well as
 *   - |RIGHT-CLICK->OPEN LINK IN TAB|.
